If you search on Google for "Why Bitcoin is falling" you would find dozens of articles full of BS explaining to you nothing, so let's keep it short and sweet:

• The collapse of Luna and UST is one reason
• During the collapse Tether (USDT) hit $0.95 - it could happen again and this time go south
• Bank run on Celsius - the model of lending/high interest doesn't work well if central banks around the world raise interest rates and make it unattractive to look for such products as a result
• BlockFi and Crypto.com cutting off 20% of its work force:

• Binance US sued over promotion of Luna and UST:

• Binance in general is under lots of scrutiny, the SEC is investigating its currency - BNB, the IRS earlier launched a probe against them:

All in all, a big crash can come from either Binance or Tether's direction (or maybe USDC) - if the US govt would want to stop the use of USDT/USDC tokens - they can do it at any given moment!

All in all - there is no trust in the system, and when there is no trust - there would be a crash in the price, "because markets are ruled right now by fear" (Alessio Rastani on the BBC, when the Eurozone was in troubles).
