Not at all. Why would I care about the opinion of someone who doesn't understand Bitcoin? It makes absolutely no sense. Bitcoin has been subject to a whole lot of unwarranted criticism by banks, governments, insanely wealthy individuals, etc. It didn't have any impact on Bitcoin at all, because most people know better than that. The entire crypto market is progressing in a rapid pace, and with that comes a better overall understanding of what Bitcoin is about. Let people talk whatever they want, if they don't understand what Bitcoin is, and aren't able to come up with justified constructive criticism, they at all times should be ignored.
I'm not even sure if he understand what bitcoin is, too. He's an old person and they don't understand very technologic things such as bitcoin and blockchain. So he made wrong negative comments on bitcoin, I found his arguments are wrong.
He understands what is bitcoin, what he is trying to do is to calm down his investors who are thinking to move money from his investment companies to cryptos. He is not first who say that bitcoin is one big scam, many before him done the same and all of them are from investment, banking, government sectors. Bad comments about bitcoin is something that I'm use to see since I'm here, and what they are saying is completely wrong and fact is bitcoin itself, where it was before and where it is now, community is growing, price is growing, bitcoin is stronger then ever before, anyone who search a bit more about bitcoin world will realize that after couple minutes.
