Is it safe for a Bitcoin trader to quit their jobs and focus solely on Bitcoin trading if they can devote their time and attention to maximize the benefits in the Bitcoin world?
It's safe but one that has become full-time in trading bitcoin has understood the risk that he's going to take. I advice you not to quit your job while trading bitcoin.
You can do the same thing at the same time without even the need for you to resign from your job. This is a risky market and volatility shouldn't be taken easily since you're still new to this. A full time trader can't only be found in Bitcoin but also in other markets like stocks, you'll see people that have committed and decided to go full time with those because they know that they can.
