Current cryptocurrencies that are popular today like Bitcoin and Ethereum have many problems (transaction time, can't be used day-to-day, dApp support). We're in the fight for who can invent the best crypto for the future, so it makes sense.
well it is true, now an awful lot of companies that are developing new crypto menciptakn and with better technology and fast. If later there will be a crypto can be used as a daily transaction I think it would be very useful.
