Critical? Then you must not have gotten rich/must not be money material!
This is quite literally the line used by "energy deregulation" MLM hucksters.
It's OK to admit that you're enthusiastic about something because you think it'll make you rich. Heck, it's even OK to promote it because you think that will help pump things in some small way (or a large way, depending on which sketchy Telegram chats you're pumping it in).
But don't BS others, or yourself, about your reasons for doing this.
The music's been fading out for a bit. The world changing innovations didn't happen, the grand plans were very nearly all vaporware, and the few that were even arguably real have come to naught.
It doesn't take any bitterness to come to an overwhelmingly negative opinion about this entire area and anyone even somewhat bullish on it.
Tether? Scam. Ripple? Scam. Most shitcoins? Scam. Crypto as a technology? It's just code, and open source (usually) and you personally can get involved by submitting a PR.
People buy stonks with VERY little understanding of what makes it worth something. Same shit
