in my opinion bitcoin is now accepted world wide and it is valuable because many people use this for online trade and with this online business is promoted well it is good to keep our coins with exchange and use this for a good and faster transaction while some time you can convert into other coins, Now crypto is very important because we have to move with the world and it is the modern weapon with us.
While it's true that Bitcoins is accepted globally let's not forget many countries do not accept bitcoins, while some lack clarity on the rules, some had declared it illegal. Another major issue with using bitcoins is the volatility in it's prices which are not stable. I differ on the speed of transactions I remember my own transaction which was stuck for 72 hours, and at times even more for some though these days it's getting faster merchants would be vary of using it. Last but most importantly regulations and taxes to use bitcoins one needs to study the regulations and taxes that come with bitcoins, which gets costly and time consuming for merchants.
