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, it is still depends on how huge the people will support the cryptocurrencies. for now it will still go for long term because more and more investors are supporting it and the market still have trading.
