We need this to have a competition so developers will trigger to do their jobs. And if there is no competition there is no market. If there is no market there's no fund for development of bitcoin.
but, now cryptocurrencies is more than enough,, and a lot of dev gone after their project dead and have no value,,
so, in my opinion we need only a few solid altcoins with serious dev my friend,,
because depends at coinmarketcap for now its more than 2000 crypto in the markets,,
and a lot of them have no value
