1: I have talked with them about this in neutral matter, and while i haven't said it to them, last thing i would want for them is to be anywhere near this space. They have actual real life skills in a level that pretty much guarantees them a good salary. No matter if they choose to be entrepreneurs or workers.

2: Scamming would probably be most profitable sector.

3: Most "jobs" in this sector that don't require much skills have always been either saturated by cheap labor, or botted out when ever anyone has noticed that there's a market to profit.

Rest of those are development jobs, but most of them don't produce anything tangible. It's just bunch of influencers creating value via speculation and their wealth growth models are indistinguishable from any pyramid scheme. So, no. I don't want my kids going for same road as me in this. If they want to invest, that's their choice, but that's not a job.
