Most potential investors are hiding behind the walls because of the fear generated by the governments in regards to cryptocurrency. Once crypto gets the approval of all governments, both new and some old investors will invest without much fear and this will increase the demand and usage of crypto in our daily lives. The value of the market will increase as well.
I think if government is going to embrace the cryptocurrency, there will be a big increase of its market cap and market value. But, expect that they might have an authority to somehow control it in their ways. It is will used in their projects and the development of the country itself.
