as long as they understand what it;s bitcoin and how to bitcoin working they are entitled to use bitcoin, for people who do not know bitcoin I hope they seek to know first about bitcoin before using. bitcoin can be used by anyone
Understand is not enough, the biggest problem is bitcoin can not be used directly, this may be the Government not approve to use the bitcoin, moreover fiat money is still popular and can accept anyone and easier than bitcoin.
It is true, an understanding is not the important thing. The reason is not the only place that bitcoin is understood only and then they use it, bitcoin is a place to make deals that are very profitable. If it is true that the Government does not accept or approve bitcoin, then it is not a matter of right. Because the Government also does not have a strong enough influence in the price rise, so things should be taken into account is on the decrease of demand bitcoin which can lower the price of the bitcoin and stability
