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.
Another form of ponzi scheme again. You shouldn't believe on what they showed blockchain record to you those are artificial only which means fake. Just think they will double your fund or investment do you think where there gonna get the payment to make it double of course to the next investor after you, all payment will come to the investors, more on referral system etc. avoid such things like this pal.
