Raised by gamblers propagated by Elon musk he is DogeCoin
I know Doge when gambling so what will happen if DogeCoin is not available at gambling? yes dead

I know this coin is mostly used in gambling I don't see any other function besides that.
Yes Doge is used a lot in gambling however Doge is also used in transferring funds from one exchange to another because of the low fees compared to other cryptocurrencies. I always use Doge to transfer from one exchange to the other as it has saved me a lot in fees over the years and I know a lot of people continue to use Doge for this reason also.
