I also think it's a very good thing to get a lot of FIAT into the actual backbone and infrastructure of Bitcoin and not only into the currency itself. Sure, it's tempting to see millions of USD flowing into BTC, but the ecosystem needs to sustain and justify the high prices, as well!
it is good if you know what you are doing and have good capital. Otherwise you might do bad stuff or get scammed and lose all your money.
For people that don't understand the technicals buy BTC might be better
Exactly it means people have
faith in the big companies behind bitcoin (The companies help to give it value imo)
Bitcoin is not a religion (though it seems to be for a lot of folks around here).
There are always die-hard fanatics... It doesn't matter what topic. People can be fanatics about sport, music, cars, watches, military, wine, and also currency or technology. It's not a Bitcoin-specific thing, really...
