For sure, no matter how hard they try Bitcoin accumulation and its usage will keep on increasing day by day until dey have nothing to fight with. That is, Bitcoin will became too powerful for dem to even restrict their citizens from adopting it. Because I believe that a time will come were if your economy does not accept Bitcoin you'll bee seen as a less developed and ignorant nation. Currently bitcoin and other cryptocurrencies are on restriction in my country but that does not stop me from accumulating bitcoin or increasing my crypto portfolio, they can restrict us but they can not stop us.
accumulation of bitcoin is a good option because one day government will surely permit its investment and transactions. As quick bitcoin is becoming acceptable so it seems that in near future every country will remove restrictions which they have settled to not use bitcoin. Decentralized technology is the main characteristics of bitcoin so may be this is the reason that bitcoin is not accepted by government of a country but its not a harmful feature but there is a benefit but if one understands this fact.
Bitcoin is going more stronger so if one country see the success of other countries then there will be a possibility that every country will soon accept bitcoin. If you are still buying more and more bitcoin so it is possible that in future you will be able to take benefit from it as Bull run occurs after every four years. Restrictions will not persists always so everyone should accumulate, once bitcoin attain maximum value then there will be contrition for those who did not accumulate on time.
