Not one or the other of these ventures have a substantial use-case. 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.
I guess next 10 years would be too far away to speculate about these "just memecoins". But, we could expect anyone of these coin to be getting a new usecase which will get that to be sustaining along with bitcoins. I am confident about dogecoin to be excelling along with spacex adoption. If Elon Musk will not change his mindset then there will not be any changes in the progress of dogecoin's growth. But, I am always afraid of Elon Musk's swing mood and withdrawing support for cryptocurrencies.
As for now, I still couldn't expect huge from Shiba Inu, not ven from Doge. Although Dogecoin has been existed in the market for several years but can't just see it increase its value (not that shilling matter made by Elon). But for sure this project will remain as many traders are still able to use this. But to know that they are meme coins, that something it gives us the doubts.
Well, it has to know that it still matters how we manage them. In fact, many investors have been in huge profit investing these projects during the hype, they are in perfect timing. Thus, if we could still afford to take the risk out from them, that was our choice either.
