If the price is always going to up, i want to fulltime with bitcoin
It is really risky if you are going to full time with bitcoin because the price is quite unstable at all so the amount you are going to earn is going to depend on how much the price of bitcoin, if the price of bitcoin is going to be high then you are going to earn higher. If the price is going to be low then you are going to earn lower just like what is happening today.
Before you are going to shift to go full time with bitcoin it is better if you are going to think about it for many times. Maybe a hundred times, because you are now choosing the industry that you are going to make yourself for a living. So, it is not just like deciding that you are going to choose and suddenly you are going to quit.
