A widely followed crypto analyst and trader is issuing warnings on Bitcoin (BTC) and Ethereum (ETH) while updating his outlook on Sui (SUI) and Sei (SEI).

Crypto analyst Ali Martinez tells his 159,200 followers on X that the TD Indicator, a tool that identifies potential trend exhaustion and price reversal points by counting a sequence of price bars, indicates a warning to BTC traders.
