Hello!
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?
It will become useless when the price goes to '0'.
But do you guys think it's possible? Even if the last bitcoin is mine, people will still continue to hold and trade it. Well, we don't know what the price could be but it definitely will not be '0'.

yeah we dont know. but everything is posible right ? is like real money in this era, i believe the price will be goes to 0 after we all using debit card.
