I see so many services offering to double, triple and multiple in all possible amounts the coins you put to them. This doesn't sound very convincing to me but some of them are offering the list of blockchain transactions as a proof that coins were credited. Is this pure scam like I think or is there a possibility to realy make some coins? Would like to hear your thoughts and experiences.
DOnt fall easily into these kind of proofs because some are just for show off that they do really pay but those are just fake and if you are easily got hooked then say goodbye to your money specially to those investments who offer to good to be true high roi in a short period of time.So stay away from this.
