Can US citizens use BitMEX?

Could you please clarify for me, in light of the various regulations and restrictions surrounding cryptocurrency trading platforms, whether US citizens are permitted to utilize BitMEX for their trading activities? It's important for me to understand if there are any legal barriers or limitations that may prevent them from accessing this platform, given its popularity in the crypto space. Additionally, I'm curious if there are any alternative options for US traders seeking to engage in Leveraged trading similar to what BitMEX offers.
