All things has an end including cryptocurrency maybe someday crypto will worthless. For now the development of cryptocurrency still running and there is a lot of investor put their money on it. We dont know what will happend in near future but i believe crypto will still exist.
Bitcoin is doing well on the eve of Halving. I think that the price will overcome 10 000 dollars. So far I will keep Bitcoin, I will start selling it with 10 500 dollars.
