Then you can venture in a new direction to find out how to make more in less amount of time. Then you can surely make a stable living off of bitcoin.
When we do that, we'll get starved..putting it in your bank or in your wallet and wait for the price increase could not help us earn for a living.. We will starve that way..
Better invest in fiat and have a savings of about one year of your salary when you you want to quit your job..IMO, it is not easy to survive with bitcoin as a source of living...
I really agree with you we cannot earn a living for bitcoin because we didnt know if we earn today and tommorrow for me bitcoin is just for savings for me and it cannot replace the real job. So only think bitcoin is for investment and dor future savings.
