Did he mention what it is that is difficult to understand in Bitcoin or the area he’s referring to? Using Bitcoin simply for transaction, which is the main reason Satoshi Nakamoto made it, is easy than when you decide to start investing and trading it.

When I was using Bitcoin for transactions I only buy when I need to send money and also when I receive Bitcoin as payment I don’t leave it there, I withdraw it that same minute using peer-to-peer exchanges that are locally available to get the money straight to my bank. There is really nothing hard to know about Bitcoin, just get a good wallet, copy your address and send to the payee or if you’re the one sending the money you ask for their address and copy paste, then send. So what’s hard in it? People just don’t want to use Bitcoin, there’s nothing hard in it.
