I don't recommend spending all of your bitcoin in trading. Unless you are experienced one (in the first place if you are experienced you will not ask that question). Now, based on my insights you were starting to trade right? So, I'd recommen just put a little amount of bitcoin as you were only practicing and getting some knowledge and ideas on how is the trading going on. Now, when you mastered in (takes some time) you can now put larger capital so that you can earn bigger profits in every trade you can make. But jutst some tips, only put what you can afford to loose ssince trading involves risk of loosing money.
