I fully support the use of ETF VanEck-SolidX Bitcoin .
This will change the opinion of institutional investors. Regulation in the form of prohibitions will not have a positive effect, since the block chain is decentralized in form. Cryptocurrency is just one of the tools for investment and should not be viewed as a negative phenomenon.
