Does anyone remember those years when you collect thousands of doge coin from crypto faucet sites back in 2018/2019?
I remember I was new to crypto then and I accumulated lots of doge coins.
I made a big mistake by swapping those doge coins for bitcoin cash.
Dogecoin and Bitcoin Cash are Proof of Work altcoins, and they have never been Smart Contract altcoins so there has never been swap features for those altcoins.
You sold your Dogecoin and used money from it for purchasing Bitcoin Cash, it was not a swap between two altcoins.
Recent years, there are many wrapped tokens and I did not check but it's possibly to have Dogecoin wrapped tokens, Bitcoin Cash wrapped tokens but remember those tokens are not Dogecoin and Bitcoin Cash. You can lose money by owning those wrapped tokens if they lose pegs to either Dogecoin or Bitcoin Cash.
