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 
i will become bias but im not into gambling so my answer is Trade only,yeah trading has a bit of gambling as we really know perfectly what coins wont grow yet we are putting funds towards that coin..but i rather choose pure trading that has small amount of losing.while gambling only relies on luck and nothing more
