Where to buy Onyxcoin in Spain

Since 1 July 2026 only platforms authorised under MiCA may operate in Spain. These ones are and have the pair open — two different things, and both worth checking. You can verify the authorisation yourself in the register we keep up to date:

Is this your first purchase? Before opening an account, read how to buy cryptocurrency in Spain step by step: the right order, what they will ask you for and what you pay extra if you press the wrong button.

  • Kraken — XCN/EUR, XCN/USD. You can pay in euros. Payward Europe Solutions Limited, authorised by Central Bank of Ireland (CBI) since 06/2025.
  • Coinbase — XCN/USD. No euro pair: you would have to swap into another coin first, and that swap is taxable in Spain. Coinbase Luxembourg S.A., authorised by Commission de Surveillance du Secteur Financier (CSSF) since 06/2025.

Being authorised does not mean they are the best option for you: it means they may operate legally. Fees and service are something you have to look at separately. This is not investment advice.

Availability checked on 14/09/2026. We cannot say either way for Bitpanda: it does not publish its list of trading pairs.

And when you sell at a profit, it has to be declared: work out what you pay in Spanish income tax using the FIFO method the tax office requires. And if you hold more than €50,000 on platforms outside Spain, you also have to file form 721, which is informational and costs nothing.

What is Onyxcoin

Onyxcoin trades under the ticker XCN and ranks #205 by market capitalisation in the CoinGecko catalogue. It is a token issued on the Ethereum network, not a coin with a chain of its own.

Why you will not find a price prediction here

There is no method that reliably predicts the price of a cryptocurrency. It depends on regulation, on adoption, on interest rates, on the decisions of a handful of very large firms and on market sentiment — none of which follows from today's price. A figure twelve months out would not be analysis: it would be an invented number that looks like data.

What you can look at is right above, and it is verifiable: the all-time high and low with their dates, how far away each one is and the recent path. With that you decide for yourself, which is rather more than a figure with nothing behind it gives you.
