In my opinion, Cryptocurrency will last a very long time. because, Cryptocurrency is so much in demand by people even some countries have started legalizing Cryptocurrency as a medium of exchange.
even so, cryptocurrency must continue to innovate that can be accepted by the broader community as a solution to transactions that are easy and safe not only limited to prices in the exchange market pioneered by traders and investors so that cryptocurrency will survive and run as expected
Cryptocurrency will stay, it's here and waiting to be develop, if bitcoin will survive, the rest will also survive.
It will need time to develop, people are investing now thinking they can get good profit as the demand increases in the future, they put
risk by doing that but they believe on the potential of crypto.
