This legend of the "one man show" may not be correct. The message refers to "we" and also years pass and things evolve, maybe he let other people iinto the project.
It's not a legend. Using "we" doesn't anything - most services use it even if it's just man behind them, it's just look more solid. Maybe something has changed and he hired some more people, but considering how things are done on Coinpot, I doubt about it.
