I will suggest you give us review of those platforms you listed or link for interested people to research on them for trust sake. It is not just to list brokers accepting bitcoin deposit but how trustworthy are they in every aspect of trading plus manipulation or withdrawal. It is a sensitive post that you have made and I hope newbies won't start patronising them but won't be able to withdraw profit. Trading is about our capital involved and we have to be careful whose custody we keep it. Accepting bitcoin is not just what matters as far brokers is the issue.
I really appreciate your concern and I know how hard it can be when you can’t withdraw your profits. You not only lose money but your precious time and efforts also. All these brokers that I’ve mentioned are low deposit brokers and offer micro lots. In case of any doubt, one can test them by withdrawing small profits initially. If you find anything fishy you can always step back.
