There are very few offshore brokers that accepts US traders. I helped a friend of mine setup an account with Forexchief. He uses bitcoin for deposit and withdrawal. We usually take money off the wallet to an offshore account due to the none stable nature of bitcoin. Whenever he wants to deposit, he moves money back to wallet and deposit immediately. If you have this kind of setup, you can trade with any broker.
I can do coinbase btc transfers, bank transfers, debit deposits, paypal, skrill, the issue isnt transferring, I need a reliable offshore broker that wont hold my deposited money/winnings and can withdrawal anytime and get it in a timely manner
So far I have come down to only a few choices
Turnkey forex
Coinexx
Eaglefx
For traders who used these four, how is the experience overall for these four brokers ?
