Re: Should I wait to have a huge capital before I start trading?
As it was said, it's really better to start off small, because sometimes market can still be unpredictable and wreck us 
Using the limits both for going onto the positions and for the trading session overall is the best course of action, in my opinion.
Well, market is always unpredictable but someone who's good at trading then that person will still make profit even by starting small or large. A good trader can earn profits no matter how market behaves but surely if that trader only trades Bitcoin not other coins. However, someone who's new to trading won't be able to earn profits in unpredictable market. Using the limits both for going onto the positions and for the trading session overall is the best course of action, in my opinion. It's true that a good trader can make profits even in a falling market but if he uses a small capital then the profits will be small.
On the other hand, if the initial capital is bigger then the returns will be bigger as well.
If the trader is a pro, then he can surely use a bigger capital but if he is a newbie then he should definitely start with a small capital only.
