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.

  • Bit2Me — SC/EUR. You can pay in euros. Bitcoinforme S.L., authorised by Comision Nacional del Mercado de Valores (CNMV) since 10/2025.
  • Kraken — SC/EUR, SC/USD, SC/XBT. You can pay in euros. Payward Europe Solutions Limited, authorised by Central Bank of Ireland (CBI) 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.

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 Siacoin

Siacoin trades under the ticker SC and ranks #497 by market capitalisation in the CoinGecko catalogue. It runs on its own blockchain, using the Blake2b algorithm. Its genesis block is dated 6 June 2015. CoinGecko lists it under smart contract platforms, decentralised storage and decentralised physical infrastructure (DePIN).

Project description from CoinGecko

Sia is a decentralized cloud storage platform similar in concept to Dropbox and other centralized storage provider where instead of renting storage space from a centralized entity, clients rent storage space from other peers. The only difference is Sia uses blockchain to facilitate transactions Nodes provide storage to clients using the Sia blockchain as contracts. Before storing the data, the data is encrypted into many pieces and uploaded to different hosts. Siacoin is created by David Vorick and Luke Champine of Nebulous Inc. As the traditional storage platforms are higher in cost, more expensive and data is not well protected. Siacoin promises to offer secured storage transactions with smart contracts which is more affordable and reliable. Moreover, it is completely open source which means many individuals have contributed to Siacoin’s software hence there will be an active community building innovative applications on top if the Sia API. In 2018, Siacoin aims to introduce file sharing and be the go-to cloud storage platform for companies. Their goal is divided into 3 time frames which are short-term, medium-term and long-term development. Short-term development focuses on file sharing between Sia users. This allows Sia users to share files in the platform without having to take it off the cloud while increasing network utilization. Medium-term development’s goal is to enhance partnerships. This means reaching out to large companies like Netflix and Dropbox to hopefully be able to be their storage and distribution framework. Lastly, long-term development aims to expand its horizon to share files with non-Sia users and support mobile wallets.

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.
