it is very true what you convey in your opinion crypto or bitcoin currency in my opinion was created using the times and technology and of course it can be used in countries that are developing in terms of economy or technology and I think someday it will be needed in developing countries of course

It is quite normal that more developed countries use advanced technologies more. Over time, I think other countries will catch up.

i think the reason is that they all have good understandinthat bitcoin will lead it to future payment , and they have good acess to it

In my opinion, this is logical. Buy bitcoin at such a high price can only in those countries where there is a very high level of income of the population. In addition, the occupation of cryptocurrency presupposes the presence of a sufficient amount of free time and a certain technical equipment. If people in poor countries from morning to night earn themselves and their families for a piece of bread, they will clearly not be up to cryptocurrency. Most likely, they will not even know about it, and if they hear it, they will not be able to use it, because the cryptocurrency requires certain knowledge and skills.

It's because there are more people that are interested in current trends of technology on those countries. Some big merchants there helps to promote bitcoin. People keeps exploring ways to make their life more productive and efficient. Unlike other countries they stay to the traditional or usual way of doing transactions. And not many people in thst country knows about bitcoin.
