You are right but not all coins in crypto market, but new projects. all the top coins have achieved what they promised investors in AMA sessions, such as Binance promised to buy back the coins and burn, they did.
  The problem here is that we should not rely too much on the promises of shitcoins, because the CEOs just want to make money from investors and run away.
[/quote]So do not ever involve large amounts of funds for new coins or tokens. That's a high risk. It is better to choose a project from coins and tokens that already exist and are proven to show good development of the projects that they are developing.
