After 10 years, I wouldn't be surprised if the man decided that he had enough money to end the whole thing and maybe devote himself to some new challenges. Some are surprised by this, as if a person has committed to providing a service for life, and how many people have been active on this forum for 10 or more years - or how many will be there in 10 years?
Especially with all the regulatory uncertainties. These days you have to watch the regulators all the time. One day they are ok with what you're doing the other day they attack you, like the SEC did with staking in the US.
It's not the crypto system that is broken and uncertain, it's the politics and the corrupt financial system that is making crypto volatile. I wouldn't want to run a crypto company if they could raid my house at any time claiming my site accepted coins from a hack or I don't have a money transmitting license or something else.
