Well, if you think that everything is so easy in here, why do not you invest $1 and make $1500 in just a few days just like you are saying? Maybe you do not know it, but you are the new Warren Buffet, the master of finances!
Put 50 bucks on a x5 coin on short term sell when the investment hits 250 USD
Long term HODL your 250 buck on a x100 coin (better if U find a newly dumped ICO)
Be realistic, you will never turn $50 on $25000, are you crazy? that is not possible. And the only ones who could make that profit were those who had a huge luck on the past.
Or those who "invested" in an ICO and it suddenly made a x15 or a x10.
But a x100? No way, that is not happening anymore.
