Many people have humorous thoughts about various SCAM incidents in the crypto field. There is no right or wrong, just different perspectives. Currently, I am improving myself not to judge anyone's viewpoint. But here are some examples:
1/ Projects with F1, F2, F3, F4, mostly are multi-level scam projects.
2/ Projects that raise funds and then do nothing at all are also scam projects.
3/ Projects that raise funds, build, but run out of time, are not necessarily scams!
4/ Setting up a trust to trade on your behalf, losing, burning accounts, could be prosecuted by law.
5/ Setting up a trust like credit institutions, only storing and advising, but the decision to buy or not is up to the investors, legally speaking, traditional finance is not wrong; if it were wrong, Blackrock and other funds would have been gone a long time ago.
6/ Not all investment advice is worth following. Yet many people still have their opinions. For example: those who advised buying BTC at the peak in 2017 at ~19k, what happened by 2020? It dropped to 4k; do you accuse them of being scams? Projects with companies, visible, legally complete, meeting the strict standards of major exchanges, having a representative company in a certain country that accepts them, even if the token drops, how is it different from other altcoins that are done properly? If you want to accuse, try to see if you can? (or does it resemble case 5)
And of course, the 5 points above are my personal opinion; in the traditional sector, there are also shark tank startup programs, 90-95% of fundraising projects are also ... failing. Accusing faith? Unless they raise funds and then run away, doing nothing at all (like point 2), then "it could" be a scam. Because crypto law has not yet been established, we need time to consider this more carefully!
