I believe 99% crypto projects have 5 years lifecycle or even less. They become dead
That's why for longterm investment you'd be better of investing in altcoins with big marketcaps. They have enough money to keep their project alive.
Oyster turned out to be a high risk high reward project after the fall. I suspect the devs didn't sell enough at $3-$4 levels.
In current scenario almost every project looking very risky due to very long bear market. I also agreed with you if dev will continue to showing their support and keep developing this project to make it best than it will bring more big reward in future.
