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?
All stablecoins that are backed by gold or dollars, are centralised, as they need a company that will hold this collateral. Decentralised stablecoins will be either without any collateral or will be backed by crypto. The most trustless and decentralised stablecoins are certainly algorithmic stablecoins that are regulated by arbitrageurs, but I can't recommend you any of them, as they are still not very reliable. So the best choice for you will be DAI I think.
