If doing it full time, starting from let's say $10,000 to play with, and btc being in between the same volatility now and how it was about a year ago when it was at around 6k..what could you net a month, realistically?
In the current market situation where almost every altcoin is going up you can make a lot of profit, minimum 2x-3x on monthly basis. But this ratio of the profit making will decrease in bear market and at times you won't be able to make any profit. I would not recommend you to do full time trading with only capital of 10,000$.
