Ultimate Guide on How to Buy Altcoins: For Fiat, For Bigger Crypto, With KYC, Anonymously (BitStamp, Kraken, Bitfinex, LocalCryptos) - #CryptoTrading

Published in Onramp · Labeled as onramp ·

Comprehensive guide on how and where to buy cryptocurrencies for fiat with or without KYC; and how to buy small-cap altcoins for other crypto.

The crypto markets changed a lot over the past years. First version of this guide was written in January 2017. Back then everyone traded at Poloniex and liquid altcoin-fiat markets didn’t exist yet.

Now they do, which makes it is easier to onramp into any crypto of your choice.

We have rewritten this article to explain the different onramping routes, comparing their pros and cons.


  1. How to buy any altcoin of your choice
  2. Where to buy altcoins for fiat with KYC
  3. Where to buy altcoins for fiat anonymously (no KYC)
  4. Where to trade small-cap altcoins for other crypto
  5. Where to buy and trade cryptocurrencies as an American

How to buy any cryptocurrency of your choice

Wherever you are based, the idea is always the same: Once you have bought some crypto, you will be able to exchange it for the cryptocurrency you actually want to buy.

That’s why buying large-cap cryptocurrencies is sometimes called onramping.

They are your gateway to small-cap altcoins, DeFi tokens, derivatives, staking and yield farming.

There are ways to onramp from fiat to crypto even if you are American, and even if you don’t want to do KYC.

You pretty much only need to decide where to buy your initial gateway cryptocurrency and where to trade it further, if that’s what you need.

Where to Buy Altcoins for Fiat with Identity Verification (KYC)


  • Accepts EU, US and most of the world (SEPA, wire)
  • Banks in EU (Slovenia)
  • Altcoins Ripple, Ethereum, Litecoin (large-cap only)
  • Experience ★★★★☆


Bitstamp is a reliable exchange.

If you bank in the EU, you will be using the SEPA payment to send fiat in or out. It clears quickly and costs not much.

Bitstamp accepts US customers too, but it is less convenient for US traders to wire money to Slovenia.

Bitstamp is a good choice for people who bank in Europe, have no intention to actively trade, but want a reliable exchange to buy crypto from. Bitstamp even provides super simplified instant buy interface.

Join Bitstamp


You need to be fully verified to even access Bitstamp: ID, proof of residence, selfie.

Certain account worth changes trigger additional KYC, such as questionnaire inquiring about how much you are about to traded and why will you be doing that.

The trading engine is slow and fees too high for active trading: Bitstamp rounds up the fee for every partial purchase which makes the whole trade relatively expensive.


  • Accepts EU, US and most of the world (SEPA, wire)
  • Banks in US
  • Altcoins Ethereum, Litecoins, DeFi tokens (mix)
  • Experience ★★★☆☆


Coinbase is the most popular exchange and crypto wallet in the US.

For US residents it is supper convenient to deposit in there, buy crypto on the exchange and keep it in the wallet. They also have an EU bank account for EU residents.

Coinbase lists a mixture of big and small cryptocurrencies, which makes it the easiest way to get exposure to new tokens (DeFi, anyone?).

Join Coinbase


In 2017, Coinbase lost a court case with the IRS and is obliged to share user data with the IRS.

They are capitalizing a lot on the fact that the noobs choose them. (Not that it’s terribly wrong, just saying.) You can buy directly through the wallet but the fees can get crazy. The regular exchange market with normal fees is at Coinbase PRO (formerly GDAX).

  • Coinbase Wallet instant buy fee: between 1.49% and 3.99% depending on method
  • Coinbase PRO instant buy fee (AKA market order, fills right away): 0.25%
  • Coinbase PRO limit buy fee (AKA limit order, fills when the market gets there): 0

Last negative is that Coinbase is tracing where your crypto came from. If you decide to sell a coin you didn’t store in Coinbase wallet, but its previous owner passed it through a casino or a darknet market, Coinbase will detect it and shut your account down without warning.


  • Accepts EU, parts of US and most of the world (SEPA, wire)
  • Banks in Who knows. Company resides in British Virgin Islands.
  • Altcoins Plenty!
  • Experience ★★★☆☆


The Bitfinex trading interface has no contender, both in desktop app and on smartphones.

The mobile app has configurable permissions, so you can allow only the lending functionality for instance - in case you are worried about your phone’s security. More here

The exchange offers spot trading, leveraged trading, OTC, margin funding and derivatives exchange. Fees are low and get lower with traded volume.

Verification is not required but you will need the full verification to purchase for fiat.

Bitfinex was hacked in August 2016.

Its flagship IOU stablecoin Tether was hacked in 2017.

Their customer support can be unresponsive, and the interface will be a huge overkill for someone who just wants to buy and hold. Bitfinex is far more suitable for active trading than for plain buying.


  • Accepts EU, US and most of the world (SEPA, wire)
  • Banks in US, EU
  • Altcoins Plenty!
  • Experience ★★★★☆


Kraken offers easy to use interface for simple buying, and even easier to use OTC. The bottom limit for OTC transactions is only 100k USD, trades are done via Telegram.

Kraken is the exchange with the most solid banking, and was awarded a banking license in 2020.

KYC is required only to move fiat (ID, proof of address).

Kraken is the best choice for US residents to buy cryptocurrencies.

Join Kraken


Kraken used to be the least reliable crypto exchange, the platform would crash all the time, but they seem to have gotten their stuff together. We’ll see how they’ll hold up during the next bull market.

The trading interface is still pretty janky. In a way, Kraken is the perfect complement of Bitfinex - Bitfinex is better for trading while Kraken for plain purchasing.

Independent Reserve

  • Accepts EU, US and most of the world (wire)
  • Banks in AU
  • Altcoins A couple, mix of large-cap and new DeFi tokens.
  • Experience ★★★★☆


Independent Reserve is an Australian crypto market that is catered towards plain buying, similarly as Kraken does it in the US.

Their main advantage is a built-in scheduler which makes it easy for long-term holders to DCA in or out.

They have an OTC desk.

Support is pretty good.

Banks in Australia, so your wire will take a while.

Their trading interface is super basic, again - this is an exchange for simple buying, not for daytrading.

How to Buy Altcoins Anonymously (Without KYC)

There is only one reliable platform that will let you buy crypto nonymously without KYC and that is LocalCryptos.

LocalCryptos are NOT related to LocalBitcoins, a platform that can be no longer recommended.

LocalCryptos is a zero-knowledge dApp to which you sign up directly through your MetaMask or other crypto wallet.

You own the private keys of your crypto, which means the platform will never have a reason to ask you for KYC, since they don’t work with your crypto at all. You are still the sole owner of your cryptocurrency.

A trader you are buying cryptocurrency from might ask for your documents to lower the risk of fraud. This is not exposing you to the platform because the messaging system on LocalCryptos is end-to-end encrypted. Even if a government agency asks for access to your messages, LocalCryptos cannot provide it.

LocalCryptos lets you buy ETH, BTC and LTC for fiat and via other various forms of payment. On LocalCryptos you get the classic version of BTC and LTC, the dApp uses Bitcoin/Litecoin scripts for the code of its escrow system. Scripts are native to Bitcoin and Litecoin blockchain.

How to Buy Small Altcoins for Other Crypto

Buy and hold small amount of altcoin

For crypto-to-crypto trades, the regulations are typically far less strict than for transactions between fiat and crypto.

There are plenty places where you can use BTC, ETH or some other larger crypto and swap it for the small-cap token of your choice without any KYC, in some cases without any need to sign up for an account.

Shapeshift, Changelly and similar

If you are looking for the fastest and easiest way to buy a smaller altcoin for a larger one, just use Changelly.

Go To Changelly

Wallet Built-In Swap

If you just want to quickly buy a smaller, but not totally new altcoin, some desktop wallets now have built in exchanges - such as the Exodus wallet. Fees are a bit higher but for small transactions it doesn’t amount to much.

MyEtherWallet offers a similar built-in swap for Ethereum-based tokens.

Buy and hold larger amount of altcoin

For larger transactions the fee will start to matter, which is why you will want to take your money to an actual trading exchange or an OTC desk.

Choose according to your preference:

  • Bitstamp is the only one that will need to have you KYC-verified even to deposit crypto.
  • Kraken’s website can get a little cranky, but OTC is pretty good.
  • Bitfinex has the lowest fees but quite a complicated interface, if you are not a trader.

Some tips for US-based people

As most of us know, US traders are not welcome on most crypto exchanges.

Bitfinex stopped servicing verified US residents in November 2017. BitMEX stopped servicing US customers long ago but since August 2020 also enforces KYC.

Good news is that once you get some crypto, you can trade that into pretty much any other crypto.

To onramp into crypto from the US, you have the following options:

Then exchange your initial crypto for the cryptocurrency you actually want:

  • You can trade unverified on Bitfinex with no limits on withdrawals or trade size.
  • To get DeFi tokens, WhiteBit lets you trade unverified until 2 BTC withdrawals per day.
    • First 14 days are on zero fee if you sign up with this shill link.
  • If you have ETH, you can use Uniswap or any other non-custodial platform without verification.

Last but not least: Don’t leave your crypto on the exchange!

Altcoin Storage: Cryptocurrency Wallets

You have two options - an altcoin-specific wallet or a multi-altcoin wallet. In any case, it is always a bad idea to leave your coin on an exchange.
