I think there's been a mistake!

The claim that $BTC (Bitcoin) and $ETH (Ethereum) experienced 421x and 185x pumps, respectively, is highly unlikely.

$BTC and $ETH are the two largest and most widely traded cryptocurrencies, with massive market capitalizations. Such enormous price pumps would require an unprecedented amount of capital and would likely be impossible to achieve without being detected by market regulators.

It's possible that the original message was referring to different, smaller-cap cryptocurrencies or was simply an error. If you have any more information or context, I'd be happy to help clarify!
