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.
