I wanna double check something. OP, are you from UK or just somewhere else in the EU? because AFAIK, there is still a difference in products made available -- as far as exchanges who complies with regulatory bodies are concerned.
Last I checked, FCA was trying to block leverage trading for retail folks in the UK as much as possible. Kraken likely had to comply to their policies as well.
In 2020,
FCA bans the sale of crypto-derivatives to retail consumers. They're limited to spot trading. No leverage is available. Only professional investors and traders are allowed to trade options, futures, and others. Professional here doesn't refer to individuals. They refer to firms and institutions.
In 2024, this year, FCA has made
updates, but only as regards crypto-backed Exchange Traded Notes. The rest of the rules stay including the ban of derivatives among retail consumers.
Everything that you are talking about is derivative trading and not entirely leverage trading. Derivative markets are the perpetual futures, futures, options and maybe some others. But these are not the only leverage trading. Margin trading is also leverage trading in a way that you can automatically borrow funds to increase your leverage and the trading is having spot market price. According to what I read, Kraken is having margin trading.
