Not really. The true decentralized currency can never be regulated by the government. The only way they can regulate crypto currency is through an indirect way. The government can take control (regulate) those centralized exchange, wallets and crypto currencies. So anyone as long as they are not using those centralized institution or interacting with fiat currency will be able to evade those regulation.
Maybe for now the majority of the coins are under by decentralized based concept. While in the private coins example that are regulated by the government was XMR or known as Monero, and Ripple(XRP) if I am not mistaken. And there are only two thing may happens if ever one cryptocurrency enter into one country, they can ban it or regulate it or sometimes the government adopted it, same scenario with the banks as well not all of them are accepting the fact, but few of banks are accepted Bitcoin or crypto like Unionbank and more.
It's time for cryptocurrencies to implement strict regulations, the presence of regulations can convince investors to invest and avoid scam projects, nowadays many people use cryptocurrencies as a means of scam, so based on reports that cryptocurrencies are the second position for scams.
You are certainly correct Sir, the advantages of the coin once it become regulated is that, scamming the community here in the crypto space will be disappear little by little, security will be going to level up, though tax will come to us for every transactions for sure in the end. What do you think? am I right?
