I saw a news on CoinTelegraph that bitcoin has a support on top of 2021.

And that Top/support is around $69,000.

 And people (so called analyst) behind are saying that shift in Federal Reserve macro and liquidity policy. Around 45% down from all time highs (ATH) and many more. 

Some peoples are claiming exchange incidents such as Bithumb(South Korean crypto exchange) caused local panic.

And some peoples are claiming "Historically BTC has seen 40-70% pullbacks even during long term bullying market (2017&2021). 

In my opinion (I'm not analyst nor BTC investor ) BITCOIN crash reason are :

1. Over leveraging and liquidation. Leverages on derivatives exchanges like (Binance, Bybit, OKX) reached record high.

2. ETF exhaustion. Create hype, buy from rumor and sell the news. US ETF approval in 2025 caused huge institutional inflows and hype.

3. Whale profit booking. Large wallets(10K+ BTC holder) began booking profit after $120K.

4. Key psychological breakdown. Support as $100K and $80K broke quickly. 

I may be wrong as I said I'm not analyst. This is my core view and I don't recommend anyone to blindly believe in me or anyone else. Do your own research before investing hard earned money. 

Thank you for your attention 🙏
