It would help with a little more trust, but it also would defeat the purpose of what crypto is made for (decentralization), a non regulated way to exchange and store value without the use of a third party(banks/government). If people want to tax and regulate it and give up REAL CONTROL for the sole purpose of comfort and ignorance, does not need to use crypto. Regulating something only puts the regulator in power. Just my thoughts 🤷🏽‍♂️
