Not one or the other of these ventures have a substantial use-case.
The use case can be built easily when it can integrated with another dapps platform like defi, NFT, metaverse and many more. The problem is a meme coin like doge coin was not compatible with another blockchain like ethereum and doge users must have bridged their own coin to be converted into the token that based on smartcontract blockchain called wrapped doge coin. This will make them can access the use case of their coin to get at least a small passive income. that's quite different with shiba inu that is already built in ethereum blockchain that can compliant with another blockchain like polygon, matic and many more.
This gives more opportunity for shiba holders to farm, stake and so many things that will give them a lot of benefits.
They are meme-coins. Theoretical betting at best. I’d be lying on the off chance that I said I never possessed any. But fair a number of dollars here or there. These aren’t genuine ventures for genuine investors. And they likely won’t be around within the next 10 year.
So many people have been predicting doge coin would not even exist for more than 5 years but it's still alive right now. This is something that can't be predicted.
