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 
Each one of us have a different opinion of which is better to gain profit,between trading and gambling.for me gambling is good,but trading is the best,because in trading may you loss sometimes your investment but not totally your whole asset,unlike in gambling that if you loss,all possible will turn to nothing,even your own property will diminished if you become addicted in gambling and maybe sometimes will turn you into big debt,thats is to me the advantage of trading compare to online gambling,while in trading your loss will turn to gain if you can get a high potential coins have a high value in the market.
That is true and with trading, as long as you are in the exchange and are not selling yet your altcoins, you are not still in the losing or winning if the price goes down or up. However, if you do margin trading, it is kind of risky though compared to exchange.
This is the game of smart people, when we start trading we have to possess the skills already so we have a chance to success and we will not
be wasting our money.
