Bitcoin is certainly a good coin, but for example, I don’t like it as a means of using micro-payments, because the commissions are too high. For example, Dogecoin is more practical as a coin for micro payments because the transaction price is low and the speed is high. There are a lot of different coins, but they are all different and someone likes Ethereum, and someone likes Zcash, Dash or TRON. It is good that there is a choice and many different options.
