Does it make sense to believe that Bitcoin could one day be replaced by another cryptocurrency, that is, a cryptocurrency that really does make Bitcoin obsolete?
That is very hard to believe. Bitcoin has been doing fine. The flow of supply and demand are good. Bitcoin has proved its capabilities and already trusted my many investors since btc was the first digital currency. So it is very hard to believe that in the future another currency will be able to replace it.
Have you seen how much of the market cap Bitcoin is actually losing? It had 90% and now it has 39% of it.
Sooner or later the altcoins will surpass bitcoin on the marketcap.
