Not sure what you mean about "no way to have privacy in transactions". Monero already does that along with several other smaller privacy coins and even ecash.

Agree with basically everything you said. Everyone is crypto is just gambling and trying to get fiat rich for the most part. Even most Bitcoin maxis are really fiat maxis in disguise. They're hoping price pumps to sell for fiat and are obsessed about fiat price to the detriment of all else.

Yes, USDT on Tron and in general is massive. Most in this echo chamber have no clue or are in denial about it.
