This is my experience:
1Broker (no MT4): deposited till 15 BTC on account and withdrawal till 5 without any issue
SimpleFX : deposited till 150 BTC on account and withdrawal till 50 without any issue
Evolvemarkets: deposited till 5 BTC on account and withdrawal till 1 without any issue (except time for process transaction, that in some cases was arrived up 48 hours during week end)
I always prefer instant withdrawal brokers (for FIAT too - I use Exness, OctaFx), and if possible regulated broker with good standing on FPA.
PM me if you need more help about
Any good reliable MT4 forex broker with BTC as base currency for 18 BTC capital ?
Checked the brokers in the list on first page but I am reluctant to trust them with 18 BTC capital.
I search with low or no SWAP.
My main concern is they scam my money.
Evolve Market and FXCHoice look good but no automatic withdrawal is a little scary.
