For one, scamming is not only common in crypto, its everywhere. If you are to apply this kind of logic, then you should never cross the road because there's a chance you could be killed. Its all about you acknowledging the risk and being careful. The internet has a lot of opportunities but these can also be misfortunate at the same time.
I get it but with the price of bitcoin reaching new lows each and everyday, I don't even have to worry about scammers but rather about the risk of no returns on my investment. It's kind of disappointing, if we consider the lengths we went to in order to make cryptos an official mean of payment in so many countries.
