Crypto is still in it's infancy, though some have been innit since pre '08, we are still early adopters. The people talking about crypto, or write posts in here, are mostly people that's interested in tech. Sumokoin is no hyped up, marketed ICO. Peoples enthusiasm comes from spreading what the coin is all about, within the crypto community. As for longevity, this is still a young coin, but looking at what the devs have done so far. I'm confident that what's in the roadmap(
https://sumokoin.org) will be accomplished. Mass-adoption of crypto haven't occurred yet, so that's true, but when it happens the most popular coins within the community of early adopters gonna have an advantage. The frustrating part is being an early adopter and feeling that things aren't going fast enough.
What happens to fiat? Who knows, but haven't the few controlled our economy long enough?

I have a feeling that one of these "to-the-moon" days is near.
The coin has been getting some well deserved attention on social media lately. People are slowly, but surely, getting to know Sumokoin and it's bright future.
I'm really looking forward to part two of subaddresses(Nov. 30) and it being merged with GUI wallet(In December). it's going to be awesome!
I trully love Sumokoin!

Hype and speculation is not sustainable. For a crypto to have "real" value and longevity, it must have mass-adoption of its primary use case/function which is as cash/currency. But to achieve that, it must be "portable" so people can transact/trade with it on the go just like cash. Therefore, a mobile wallet should be a priority as well as cold wallet/offline signing feature on the desktop GUI wallet to secure people's stashes of the token. After all, we are our own bank in the crypto world. The devs could then add the bells and whistles after these crucial implementation to add even more value to it. First things first; not ass-backwards process. Otherwise, it's merely a speculation instrument devoid of functionality. That's why people in the know (and there are a lot of smart people in this space) always equates such scenario as a Ponzi/scam. Don't get me wrong. I would very much like to see any crypto to achieve such success (i.e. function as cash and mass-adopted) but it has been frustrating to say the least.
Just imagine what would happen to the US$, Euro, etc. if people don't use them to trade/transact.
