Unfortunately with the increase use of cryptocurrency comes losses for governments. Large amount of taxes such as income tax and sales tax can disappear from revenue agencies and this can cause problems for countries. This can mean less money being put towards building roads, local libraries or maintaining parks. Yes block-chain technology and cryptocurrencies should be able to flourish but not at the price of removing value from support programs and the financial states of counties. I am not a vindicate for strong regulations by any means but it is important to understand why they wish to regulate.
