It is good to hold Bitcoin but it is best to hold it for a long time. Some people use Bitcoin to meet their daily needs. I think these people are putting their future in danger by taking the wrong steps. Because Bitcoin is the only main tool that is needed to be economically successful.
Every time you think about it, you see that different companies and different countries are trying their best to accept Bitcoin and are providing various facilities, among which El Salvador is playing one of the roles.
Some are more ignorant than others, though.
They fear that BTC is not as good as something as big as to be in the reserves / be used as the alternative, some fear the decentralization aspect, and some - just don't want it because things are already good.
