LedgerX is a US currency exchange. So far, they only have Bitcoin options, but they plan to expand the offering.
Not just CME and Bakkton, Americans do not have much access to cryptocurrencies, so those living in countries with severe restrictions should especially look at LedgerX.
The options can be difficult to learn, but they are the easiest and most conservative to cover long pages.
So for example, if you have 1 BTC and want to keep it for a long time, you can rent Bitcoin for a month and keep it to meet the decline in Bitcoin.
