Doge will inevitably be compared to Shiba Inu dude, because if we look at the development of the two SHIB is doing better compared to Doge
LOL, SHIB is an Ethereum token, what "development" do you think is happening with it? Its governed by an immutable smart contract. It literally can't be "developed." I dunno why anybody would buy it or use it as a currency when you could just use ETH, which you need anyway to move SHIB.
although Elon Musk is promoting both when he thinks to encourage the crypto community to buy this,
He's never promoted SHIB. Somebody asked him how many he held once and he said "zero." Its not his fault if there are other cryptos trying piggyback off the community & good name of DOGE.
