Gambling is not even a profession and you open this post asking what is the best profession out there is for you.
You are correct however when you say that investing in bitcoin is a waiting game and as easy as that sounds, people actually has a hard time doing just that. They want to take profit as soon as possible but for us patience is a virtue and it will pay off soon enough.
We know gambling is completely different from investing even with futures trading they think it's different.
Don't make bitcoin investment as a job for OP anyone in investing while working you don't need to monitor the market because investment is long-term in nature, just buy and then save it is enough and set your selling target in the future.
