Okay, I know this sounds impossible but it'll look like this:
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)
Take your 25,000 and enjoy!
Is this a possible strategy guys?
There is nothing impossible... like you always have a chance to hit the lottery. This is how your plan sounds to me - a lottery.
Start making some researches in invest your money in coin or ICO you really like or support.
