I do not care about new blockchains, it might be good, it might be bad. But I wonder, if today stablecoins came out, would people really react the same way? Like how is the marketing for those stablecoins were even made, how did they convince people?
Did really someone came up and said "hey, give me your real dollars, and I will give you fake dollars that will be considered as dollars in the crypto world, I keep the real ones, you keep the fake ones, deal?" and people accepted it and it reached hundreds of billions in size.
I wonder if they can do it today too, but I never understood how that even got any traction.
Marketing? Stablecoins don't really need marketing, as they aren't building a project. They are existing project on existing blockchains. They are not bought for speculation in same way that altcoins are.
When USDT came along, it was first real hedge for unregulated exchanges to use for trading, and alternative against real fiat money. Stablecoins didn't have same kind of regulatory baggage that trading against fiat money had.
Before that it was mainly litecoin and btc pairs against rest of the altcoins. So you weren't really safe during a bitcoin bear market before stablecoins. And criticism against tether was fierce, because it stood against the whole cypherpunk ethos. Not to mention that no one really trust it would stay alive for long.
