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.
Most of the governments are not keen on accepting cryptocurrencies unless they are not decentralized or can be regulated. Cryptocurrencies are also high in volatility and posses greater risks to those who don't know to deal or manage it than the ordinary currencies. Government favors centralized currency because they are more manageable and safer to use. Only time can tell when will governments accept cryptocurrencies as legalized payment system.
