well, obviously there are the stable coins wich have the sole purpose of being stable. Tether is the most famous one )TUSD( and it is stable at 1 dollar in price. you might want to get some of that if you look for stabilty. i have heard that a new stable coin is going to launch on the stellar platform XML , and it will be a token based on the dollar price.
I agree with the cavity! The only stable crypto currency is USDT! Any stable crypto currency for half a year has fallen in price more than 3 times. Therefore, the stability of the crypto currency market is not the right word!
