Just curious since the last discussion I had was about gambling vs trading. I know trading can seem to be a bit of a gamble as well, but I see it a little bit like poker. It's a combination of math and psychology. Maybe not the same ratio though, just generalizing 
both trading and gambling has only a thin difference. but one shouldn't invest on any of these if they cannot afford to lose the money they are investing.
Well investment is a bit mild and you can set certain parameters to control it if you know your ways around it very well but gambling can be harsh and i would opt for trading any day if i was new to gambling.
Those coins that has great vision will give you better profit, of course when under development the price won't pump that hard but
eventually it will rise when progress will be seen by investors.
