My major learning from bear market:
Use a stablecoin to preserve value if you are not ready yet to convert to fiat or can't convert to fiat. It's a good that the market has lots of stablecoins now. Before only Tether was the stablecoin and there was so much FUD on it. Now we have options to somehow preserve gains/value if the value dips a lot.
If want to trade in bear market, its better using USDT pairs. Stablecoin help us to maintain our portfolio value during bear market and when we think bullish sign, we can buy bitcoin or good crypto again
