Yes, I think cryptocurrencies will stay for more than 10 years even. With the vast development of technology nowadays, it is impossible for developments of cryptos to stop as well. As of now, there are over 1500 cryptocurrencies available over the internet. I think that as long as there are people who are developing new coins/tokens, and there are still people who are willing to invest in it, cryptocurrency will continue to grow and thrive as a market. It is impossible to see cryptocurrency to die in just a wink of an eye since there will always be people who will invest in it and continue to be interested in it.
