If crypto 100% succeeds at it's goal, companies like JPMorgan get screwed, so yea.. he's not gonna talk it up. That said, if it does well enough, they kind of have to jump on board, which many of them are doing.
For anyone getting into a crypto now, I'm imagining btc will have a bit of a large correction from it's massive gains. It's corrected down as low as 13k since its peak, and it might do that again. If you are keeping close tabs and can buy in whenever its below 16k, ideally under 14k, that'd be best. Otherwise, buy it and just forget about it. It's too violatile day to day right now, but long term it's done nothing but go up. Every so often it has a big spike that draws attention to it again, but hard to tell what will trigger each one. It's often from some big company/investor putting a bunch of money into it suddenly.
If you aren't already experienced and knowledgeable about the field, it's not worth trying to get into trading and riding the highs/lows. There's a lot of research you need to do before trying that. Just like day trading stocks.
