Given the nature of this digital currency, there are always conversations to be heard about not buying Bitcoin, as Bitcoin works outside the traditional banking system, so there are too many opponents to it. However, its design is such that no one can create a particular barrier to buying it. If you have access to the Internet and a Bitcoin wallet, you can invest in buying Bitcoin.
Many countries have struggled to obtain this digital currency. Bolivia, Thailand, Vietnam and Bangladesh, for example, are all trying to obtain Bitcoin. Even more advanced countries such as Russia, Japan, Australia and Venezuela have attempted to legally sell Bitcoin. But it is interesting to note that some countries, such as India and the United States, have not yet taken action in this regard and have not yet defined an official policy on such currencies.
In general, it should be said that bitcoin cannot be an obstacle, and this is one of the advantages of Bitcoin.
On the one hand, everything is as you say, and Bitcoin is probably difficult to stop and many countries would like to use it, but there is another side that raises a number of questions that are not answered. For example, who created Bitcoin and why? There are no answers to explain this, there are only guesses and opinions. And what if someone invented Bitcoin, but could not that someone make it so that Bitcoin has the functions of management and even self-liquidation? We are told that the BTC blockchain cannot be changed or disabled, but is it 100% true? The interesting thing is that no one can 100% confirm that this is so, as well as refute it. The thing is that you and I know exactly as much about Bitcoin as they say, but there is a likelihood that we are still not being told a lot about Bitcoin, and this can be a big surprise at any time. Perhaps it is from such questions that many countries do not rush to accept Bitcoin.
