I believe that it's up to a person if they are willing to invest to a crypto for a long term investments and more crypto are existing because of it's good to invest your money to get more Profit n to it. Even our investments are not big enough like other people we are just the same investors who are looking for our benefits to the business we enter.
I agree, as long as there's traders and investors, crypto will go on, because we know that crypto's price is based on the demand. In my opinion, crypto will keep going as long as it's popular, if it's still charming to people, if crypto will give opportunities and profit to the investors and traders, crypto will last long, as long as there's people who support and buy it.
