What do i do if i lose my BTC in Gainbitcoin scam.
Not too sure if I really did, but I have come across quite a few people who did not get their refund even after weeks.
What do you mean by lose your money/btc in gainbtc? If you are not sure then asking for refund is option and they might have support system in place. So you may raise a ticket. AFAIK it is MLM structured trap, thus if you want to get out within first 30 days request refund and check with your sponsor.
Anyway dont fall prey for quick bucks without any efforts.
