The isssue i have with some of these brokers are they allow deposit with bitcoins but the dont allow withdrawal with bitcoin so its important to check very well so ypu wont get stucked while making a withdrawal
which broker are you talking about. normaly the opposite is the case.
Brokers like XM and IC markets
I just cheked IC Markets:
https://www.icmarkets.com/sc/en/trading-accounts/withdrawalit's just a fake "Bitcoin Accepted" since they use Skrill to recieve those in $s
use brokers for the list in this topic
