Guys can you give me some legit and real sites to invest my bitcoin to earn more! there were so many sites out there but i cant just invest on them because I dont know if they are real or just scam! And also do you think guys that those coin/bitcoin doubler are true?
They are all scam sites. They only differ on how long they will last because even they reached 2 or 3 years, they still end up as a scam. Bitcoin is surging very fast so just keep those and instead of investing to others stuff, buy more of them if you still can.
