Are CME BTC futures the best way for US traders to trade/hold BTC with leverage? Which brokers support it and at what margin? Amp does not, CME exchange requirement is 28k Maintenance. TD at 45k, IB 51k or so (long only, short 200k). Any other options that work with lower spread/roll costs?
Not sure if you actually own any Bitcoin with the CME as it's cash settled. Why not use a regulated broker like Kraken, they look a very well run company especially in regards to security. They also offer leverage.
