I think that is excessive, I can trade with much fewer money in the regular stock market or CFD's

wow, thanks mickey, I didn't knew that there were so many options.
The idea that I have is to make 0 inversion and have some real profits, the objective is not making me rich, but the satisfaction to get some internet pure money.
About the trading, I have a little experience, the basics, it will be also a way to practice my knowdleges with some "risk" 

Hello, i'm new
A few days ago I read a post that said that it was possible to make earnings trading with coins like if they were the stock market, and I wonder if you know any of this places to trade, and what is the minimum amount to negociate, cause I only have like 5 mBTC.
Thank you.
