In my perspective, crypto has more than one aspect; pure revolution and economy driven. One can assume that those who stay are driven by the idea behind the technology. Hence, I am still positive it will stay. Just like what I wrote above that even fintech are introducing the idea of tokens, rewards, points. This is one of the way to familiarize the mass with cryptocurrency terms.
As to my intermittent fasting, it's fairly easy but during the noon, I get terrible cravings. But I am imposing a strict rule these days it's better to cry than eat :D
