Even if we don't hope for it, regulation will happen as there's no such thing as not regulated here when the market is already as big as a billion of dollars market. The government's job is to protect the investors and the users of crypto, they won't be able to carry out their function without regulating the market.
I believe it's not a mistake since the market is already slightly regulated now and we see some good progress especially on exchanges where there's less fraud now. Let's embrace this changes as we need this, let's comply to what the government requires us and then we can see a consistent growth for the crypto market.
I am also not against legal regulation.
However, not does this contradict the basic principles of cryptocurrencies - decentralization and anonymity?
Or, probably, it will be something new, let's call it, for example, legal cryptocurrencies.
It contradicts the intention of being anonymous, though there's no way that everyone will continue using the system that have a big market value without the interfering of the government, both for right regulations or to also have a good control with how things are getting bigger with this market.
Government will ensure its position having a much higher knowledge to incorporate its ruling to prevent more people from their jurisdiction being victimized by scammers.
