A lot of bad incidences happened in crypto community this year including:

1) FTX
2) Luna
3) Gemini Earn
4) Celcius
5) Voyager
6)BlockFi

All these incidences happened because of the greed of some people. It is important to control the entry of these kind of people as developers or people behind some new crypto projects. Otherwise people will have very less trust left on crypto in general and people will move to other alternatives. What do you think are the required steps to prevent these incidences from occurring in future ? Or are these unavoidable ?
