We, all crypto users are wish a long life to bitcoin to it continue to bring us some extra profit on different ways. But one day something new will replace bitcoin. My question is - how many year you give to bitcoin before it will turn totally useless?
Bitcoin is not static, its being improved. This is one reason is has remained on top, it has addressed its own "shortcomings". And there is still more to come. Things like: faster, cheaper and offline transactions to name a few. Bitcoin is also ready to be made even more quantum resistant, and in case the time comes, it can also expand from 8 to 16 decimals. Therefore chances are quite high no altcoin will ever replace it at the top.
Why would it ever be useless? It is quite useful!
