This is where people get it wrong. Price does not move based on belief. It moves based on liquidity and execution.
Liquidity determines how easily price moves. Thin liquidity moves fast. Deep liquidity absorbs size.
Large orders move price against you. That is slippage. Most new users underestimate this.
Market cap is not cash. It does not mean that amount can be withdrawn.
Price moves where liquidity allows it to move. Not where people want it to go.
