The only harm i think scam will cause is more restrictions rules from the SEC cause scam was the reason why KYC/AML was introduced in crypto investment. However, people seems to have already understand the risk in crypto investment.
Agree. The more scams emerge, the tighter regulations will be. KYC and AML will be a requirement to get access to Bitcoin in the mainstream world. While decentralized solutions are an option, their low liquidity makes them widely unpopular in the crypto/Blockchain space. There's no denying that scams will harm Bitcoin's reputation worldwide, due to lack of people's education. If they'd learn more about how Bitcoin works, they wouldn't believe everything that's said on mainstream media. The majority doesn't care more or less about Bitcoin, as the world goes around Fiat nowadays. Bankers and governments will try their best to prevent people from using Bitcoin on top of Fiat. This means that its reputation will be in the ground, in order to make people use the traditional banking system more thoroughly. Only veterans in the crypto space and those looking for an "exit route" will use Bitcoin no matter what.
While it's true that people are starting to understand the risks in crypto investment, there's still a long road ahead. The crypto/Blockchain space needs more time to mature in order to be widely recognized as legitimate in the mainstream world. With good education, people will be able to distance Bitcoin from scams in cyberspace. Let's hope that heavy-handed regulation puts an end to scams once and for all, for the prosperous growth of Bitcoin and the entire crypto industry. Just my thoughts
