I can say that I was having difficulty finding information about bitcoin. However, I can say the following;
If for some reason you're not completely sure that BitUSD will keep its price, Bitspark's wide range of fixed currencies makes it easy to trade other currencies like BitJPY, sparkdex.HKD, BitEUR or even BitGold.
In a way, we are creating a fully functioning FX market where people can easily escape vulnerable currencies - including major cryptocurrencies - without having to pay traditional FX rates or worry about capital controls.
This is one of the great ways stablecoins can be used to deal with weak currencies.
