i lost some bitcion in my trades today , because a shitcoin went down in price 
better to trade with forex by using bitcoin, the swings there, are less severe it's more easy to follow the trend and take profit, there aren't random -300% or something like that
i would advice to trade bitcoin only if you are a part of a group that pump random altcoin
but the pump groups are all scammers who are trying to dump their own stash on other members
But if you are good at timing you can earn a lot.. it depends only on you and your feelings if you want to join something like this.. you will maybe gain some money but other will lose hard :/
