If you look at any payment mechanism which is online and uses phones and internet, the scam rates are pretty high. Because it is easier to get into a device through Trojans or phishing sites and hack a system. Also, it is easier to manipulate people on internet into giving details as digital literacy is there but that efficiently. The situation is worse in crypto because it is more complex and requires understanding of wallets, exchanges and keys which is tough to understand. Moreover, there is no central authority to look after the crimes. This increases the problem.
