Win / Loose are all points of view.

What I try to explain to newbies is that as bad as banks are, at least your money is guaranteed in most jurisdictions by the government. So if it is stolen or if the bank goes under, most of your money remains safe.

Exchanges have no such guarantees and are private companies that you are trusting with your money. If it's a small punt, fine. But never leave any serious money on them.

If you don't want to self custody Bitcoin, then consider an ETF or Saylors company as a vehicle to own Bitcoin.

From what little I know about North Korea, which is almost nothing, I know enough to know that I know more than anybody offering me an opinion on it.
