in my mind, Dogecoin has a future, but from now on they need some improvement on their system to eliminate the bad impression of users in cryptocurrency and the team wants to make the price of these coins increase, and they have to increase this coin. I think this coin is one of the old coins in the crypto world and has a good community that always supports this coin.
Yes upgrading it is very necessary, as air. Otherwise, they may not reach a more serious level, which is not profitable for them.
