One thing that not that many people are talking about is that the most lucrative ways to earn money with crypto require some money in the first place. This applies to trading and mining, at least. It's best to move gradually. You need to study lots while you still have another income, then get into different things that can start making you money. If you're mining, for example, you can just start with a small rig, then gradually build it up as you continue working and earning money. Perhaps after a while you'll see that you're making as much or more through crypto. Then you can decide to leave your main job and dedicate more to crypto. This will most likely result in you making even more money in crypto than when you were working. The two don't need to be mutually exclusive.
