Thanks for your kind reply.

...because nothing is truly stable as anything has the risk of crashing.

Oh, this sounds like something apocalyptic!

Tether does not present this same case, although it is currently stable.

Personally I would choose some stablecoin backed by gold.
Which one did you choose?
