He is not the only one, there are many other critics that have become bitcoiners eventually. I also believe there are critics who still claim to be critics, but in secret dem dey accumulate bitcoin. That is how well bitcoin don develop all these years.
That said, i no dey try force anybody wey no wan change their mind, particularly people wey dey 65 years old and above. I understand their fears and concerns with cryptocurrencies. You know say e get age wey you go reach, you basically have to reduce the risk wey you go dey expose yourself to. So if person wey dey around a certain age tell me they'll pass owning bitcoin, i can perfectly understand.
It can be true that among us here some Dey criticize bitcoin before we embrace am, and things Like Ponzi schemes their MMM and other go even make those wey Dey criticize Bitcoin to criticize am more because them see the two as same.
Yes there are critics who own bitcoin secretly, some maybe because they have businesses that them making their ownership bitcoin open go Dey bad, other go be political reasons. And as they are critics who secretly own bitcoin, some way claim to like bitcoin fit no even own any amount of bitcoin.
