so when inflation goes up, things like groceries and gas get more expensive. People tend to save money instead of investing. On the corporate side of the matter, the Fed increases interest rates to ease the inflation, which makes companies less interested in getting loans, this hurts fast developing industry such as technology the most (bc they need money to develop). In conclusion, market cools down in general, for both stock and crypto. ppl are afraid of bigger market crash like 08, so they'd rather hold more cash in hand just in case. Everyone is trying to sell and is afraid to buy, performance bad.
Some cryptos has a max cap of supply, so it can store values and has good liquidity like BTC. Besides high volatility, its new supply cut 50% every four years. In my opinion, the key is to invest long term instead of constantly trading because the market is hard to predict.
