Hindsight is 20/20, after all. If that guy didn't sell his Bitcoin at $0.30 he will probably have sold it at $8.00, at which point he'll be having the same regrets when Bitcoin hit $100.00. The story will probably go on and on.
As for Hive, it has always been a good technology way back when it was still the "other" blockchain. And now, with the mined stake gone, communities and DApps growing, and people getting interested in web 3.0, it's just a matter of time before the value of its coins match the value of the technology behind it.
