Well as to this day many countries are starting to adopt it but not totally the bitcoin itself. Some are making there own crypto for there own gains. There might come a time that btc will fall down but it will always be known as the progenator of cryptocurrencies. Adapting might be easy but making there own blockchain might be difficult. So it would be better if a country should acknowledge btc first in there owm trading for better recognition upon its citizen.
Btc will always have a room for cryptcurrency users,even there are more alts that will be created ,btc already marks its featutre and ability. It is proven and tested . For it value will soon rise still since its more convenient to use especially by newbies.
