I certainly believe in Dogecoin's future, I firmly believe Dogecoin will remain to exist as long as Bitcoin exist. No matter what will happen with other altcoins, Dogecoin will survive because we are using it, and I am using it, more than Bitcoin for doing the transactions.
as long as the team keeps active updating the blockchain, I am fine with them being inactive here.
Plenty of people use Dogecoin in exchanges by converting to it rather than use Bitcoin and other crypto to withdraw or trade as it has less tx fees.
Sure, if they the team are inactive here or post occasionally but they update the official Doge website and blockchain regularly then that really is enough. Like you I also believe in the longevity that Doge will have.
