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.
It is very clear that a country is struggling to face the development of decentralized blockchain technology, they are trying to avoid using blockchain technology with a centralized closed system by stopping all online businesses that use decentralized technology. However, fighting it will be in vain for the country, because the development of bitcoin is too strong, there are many ways to get it and the country cannot stop it.
Continuing to collect bitcoins in a portfolio is a smart choice because bitcoin will grow bigger in the future and I think gradually the country will adopt bitcoin technology too in the future. Due to the increase in its use, it is increasing day by day.
