I’ve seen Bybit, Binance and Hyperliquid mentioned quite often, but I’m a bit cautious about using offshore or non-EU platforms, especially from Germany.
Do you have any experience with regulated alternatives, for example Turbo or Knock-out products offered by my broker?
I just found examples of leverage over 20 even in Solana and Ripple.
The better for you to never use those Global CEXs and DEXs. It's because they're all have no licensed issued by BaFIN. If you're doing trade there, your account potentially to be restricted due to this.
However, some sites listed above such as Bybit and Kraken has its EU version. So you can legally trade crypto with leverage in these exchange sites.
