From my personal experience, i haven't seen a stablecoin that's actually stable, all I see been traded are coins which volatility is at it's minimum therefore they're been called stablecoins. The likes of USDT price aren't always at $1 as it was advertised to constantly be when the coin was still searching for community members to buy into their idea. I prefer to make use of my local currency to store my fund in the bear season instead of trusting any stablecoin since they're cryptocurrency too and can be easily manipulated.
