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?
I will advise you not to invest in those shady sites that promise to double your investment within a few days or weeks, why not buy some reputable coin and do it long term instead of gambling on a site that might eventually close up one day and exit scam
