Just the main ones: BTC, ETH, ADA, DOGE, LINK, LTC, SOL Not that I'd trade them all, probably mainly trade ADA or LINK. PS: In the USA. Let's say $100K account or so.
Maybe Kraken. They give 5x on BTC and ETH. Not sure about the rest. Maybe 3x on those. You can short too.
5x only? that is very little compared with trading futures/forex. I was expecting 100x or more. the higher the better. high leverage --> you put less money in your trading account / exchange. if the exchange collapses, or the Crypto CEO goes to India to die, you lose very little $$$$. but many people would say high leverage --> your terrible negative emotions (greed) caused you to put a huge amount of money in your trading account / exchange. ended up losing tons of $$$$.
Use FTX US. You need 100k$ to qualify for spot margin trading for up to 10x It's regulated, it's in the US (meaning US customers are welcome which isn't the case with any derivatives exchanges) and they have a ton of stuff to trade. Forget Kraken, it's one of the worst execution venues out there
