I reckon the best time to begin your plan for the bear market is to do it during the bull market. I want to hold American dollars or a dollar equivalent when the bear market arrives, however, I do not feel safe holding centralized stablecoins like USDT, USDC or BUSD. What are the decentralized stablecoins can everyone of you recommend?
The best decentralized stablecoin is DAI. There's no need to look elsewhere. The stablecoin has a large liquidity and a wide number of projects supporting it every step of the way. Despite the numerous benefits surrounding DAI, not many merchants and businesses accept it as payment method. The number of exchanges trading DAI are a lot smaller than those trading centralized stablecoins like USDT and USDC. With centralized stablecoins, the peg is determined by real world assets (mainly Fiat) stored in the issuer's bank account. But in the case of decentralized stablecoins, everything is governed by algorithms. Crypto collateral is used to help maintain a decentralized stablecoin's peg relative to Fiat (USD). I'd prefer a decentralized stablecoin to store my money long term than a centralized stablecoin just because the risk of loss is minimal.
Ultimately, you decide which stablecoin to use among many of them trading on the market. As long as you diversify your investment into more than one stablecoin, you'll have nothing to worry about. Just my thoughts
