Bitcoin is the father of cryptocurrency and Altcoin is the child of cryptocurrency.
 Looking at Coinmarketcap, it is understood that the trading volume is Bitcoin 60% to 70% and the rest is Altcoin volume.
 If Bitcoin was not made, Altcoin would not be made.
 Bitcoin has given birth to cryptocurrency today and cryptocurrency is spreading all over the world day by day.
 However, it is also weak Bitcoin without Altcoin.
 So Bitcoin and Bitcoin are more about friendship than war.
 This is an opinion based on my personal experience.
 Thanks.
