I wish I fully understood the rationale behind stable coins - that you clearly must get! - as I think I am still missing part of the puzzle...
Aside from the fact that they are decentralised, so less likely to be 'seized', what is the benefit?
The fact that they are pegged to the USD surely means that you risk the same slow but steady melt down of the value of your cash from inflation as holding USD directly - or am I missing something?
A stablecoin can be used as money, volatile cryptos generally are not practical as money. People want a stablecoin for the same reason they like their existing fiat currencies - they can buy and sell things at predictable prices rather than purchasing power which fluctuates wildly through the month. Inflation (at least a low rate of it) can be seen as simply a small fee for this functionality.
The benefit of a stablecoin over regular fiat currency is that you can (theoretically) use it in all the same ways as regular currency in addition to being much easier and more useful for transactions over the internet - and these days as a temporary escape from crypto volatility for traders.
Okay - thanks for the detailed explanation. Much appreciated.
