Yes, indeed... why do we have the digital blockchain dollars?
Intuitive, quip answer: to arbitrage a dollar system with, globally speaking, pretty high barriers to entry.
In this FT piece, newsletter columnist Robert Armstrong makes some observations:
Over the holidays, stablecoin issuer Tether made the news when the big crypto trading platform Coinbase announced that, for regulatory reasons, it would restrict traders in the EU from buying Tether’s coins. The market cap (number of coins in circulation multiplied by their value) of Tether’s USDT, the world’s largest stablecoin by a mile, fell a bit, and other stablecoins perked up on the news...
What is the market’s ongoing use case for stablecoins? Specifically, will stablecoins like Tether have an important role to play in cryptocurrency trading as crypto becomes more mainstream, more liquid and better integrated with fiat finance? ... We don’t use an intermediary to trade stocks, bonds, currencies, gold, grain or real estate. Why should crypto be different?
This, would seem, to be the point of Tether (profitable effing business, btw), but not its users:
the stablecoin issuers are harvesting returns on the users’ fiat (plus transaction fees!) in return for holding the cash and issuing the token. There is a lot of economic friction here.
In the long run, I don't disagree with him... yeah, bitcoin bridges like Tether or USDC don't have much purpose. But for now, in a dollar-dominated world, they do. Good luck having the EU of all irrelevant international institutions regulate them out of existence.
