If we filter the good ones (at least the coins that have :website, social media, road map,, etc) that could benefit all of us.. and who knows, your $50 investment today could turn around 6 figures in 2 years 
One coin that I believe has a lot of potential and looks quite promising is SNT (Status Network Token), but I don't think that a $50 investment in it will make me rich in 2 years. I wish
Indeed,
Every altcoin have a potential in the next year or so,but it's wishfull thinking turning 50$ into 6 figures.doesn't that mean 2000x from initial amount ? So far the best altcoins which is (i ever know) had been pumped were ;
1.DGB,back then ever traded around 30~70 satoshi.Lets assume it 30satoshi then it pumped into 2500satoshi = 2500/30:83x from initial amount.
2.XVG,in early to mid 2016ish ever traded around 1~2 satoshi and pumped into 150satoshi,that mean 150x from initial amount.
Ok,thats're some of them which is had beed pumped hard by pumper but they can not turn 50$ into 6 figures.
And the best coin for investing our money in coming year absolutly a coin that had been pumped so hard before ( reason is because some of them made a progress in their technical development which is raising their popularity ) such as DGB,XVG and any other altcoin.but we need a time to enter,because right now is not the time yet
