Well, my thought is this: everyone who doesn't believe in blockchain technology now will one day swim in their own tears. Of course, crypto time is not over! as a matter of fact, it is just beginning. crypto market crashes, just like crashes in the stocks and forex markets, are a healthy phenomenon. This occurs to get the bad ones out of the markets in order for the markets to get mature. Eventually, the crypto markets will be filled mainly with investors who truly know the utility of the tokens. that is when the real mature blockchain boom will occur. for now, all that happens is speculators focusing on market sentiments to determine the direction of price. this won't last for long! eventually, the real users will come, leaving these speculators at the back. when that time comes, only those who invested long term will rip the benefits.
So, is crypto a scam or a way to make money? well, it depends on how you would want to make the money. If you decide to go long term, build a blockchain skill and be ready to work, or maybe you want to invest long-term, then yes, it's a way to make money. however, if you are the type that wants to sit down and have money flow into your account without much work, then no, it is not.
Hard to tell, some people also lost money on blockchain technology. Nobody really knows yet how these networks will enfold and be used. And it is even harder to reasonably assess the real value of coins.
