I started trading all my deposit directly from the coins I received from the bounty campaigns. I dont feel sorry for them, so I can trade on all coins.
It can be a good idea.You can join first some legit bounty campaigns and the profit you will make could be you starting capital for your first trading.It does not make sense to start with a big capital at first knowing it can give you a large profit,for me start with a capital you can afford to lose.
