True hodlers will take advantage of bloodbaths to stack more satoshis and Bitcoin for their wallets. It is one of good times to do it. Who knows where will Bitcoin bottom out? DCA in such massacres is a very good investment strategy.
If you want to wait, let's wait for news from FED in coming hours and if the market gives you lower price, take it.
True holders will always see an opportunity to buy bitcoin at this time, while others panic to see the price drop deep. They also won't buy all-in but will do DCA because DCA is a great strategy for buying bitcoins at many low price levels. I heard the news that the FED will raise interest rates again, which could send the bitcoin price down even further. For that, we need to be prepared and don't forget to prepare your money to buy bitcoins at low prices.
