Curious to the OP's story though that he works as a scientist with a bad salary. Is it due to where he resides or to wherever he is working pays really poor?
But I think it's a pretty good job, certainly pays enough to get used to.
Actually I also have a main job, in fact I still run it and do all crypto-related activities. Even though at this time my income is greater than my main job, but I do it to maintain a clear social status. Because there are many minds who tend not to know that today's work can be done at home. Many people will think badly if we do not have a main job but have a lot of money.
