We do not know what will happen in the future, neither does cryptocurrency, but indeed, this blockchain is a fantastic technology. I am sure if the cryptocurrency coin will end if there is no community.
Future of crypto will become good as always and famous because of those people always trust on it and more people continue to trust and make bitcoin as their main income and then those people didn't believe that crypto has a great opportunity to earn money,will change their belief and will start to believe of crypto,especially for the government.
I guess that in future, we will all use the cryptocurrencies. You can pay for anything using the crypto, and it will replace fiat in some cases. Invest in the cryptocurrency to use it later - this is my motto.
