It is impossible to make the regulations of all cryptocurrencies today, which number more than 20k, a month New Listed Coins can reach 1000, maybe an easy regulation is like what Dex does, namely with liquidity, with large liquidity it will make the scam project will decrease.
Just take a very good example, the Monero coin, can the government regulate a privacy coin? I don't think so. So only few of these coins can be regulated by the government, most are those that are heavily used in the market like BTC, LTC, BNB or XRP. But about 90% of alts, won't make it in the regulation board of the government.
