Ethereum scammers are in full desperation mode now. Nobody is buying their Eth pump so they keep doing orchestrated BTC dumps to temporarily lower BTC price, make believing that will make people want Eth instead but there are just no willing buyers of that scamcoin.
That does not make any sense. BTC is still many times bigger market than ETH - suppressing BTC would involve an order of magnitude bigger loses than anyone could gain on the manipulated ETH.
Eth raised 30,000 BTC for the original IPO (most of which but not all they have dumped). There are lots of idiot traders that are currently trading BTC/ETH with an inverse correlation. So the Eth scammers do orchestrated dumps of 1000 BTC or whatever on a single exchange to temporarily give the appearance of BTC weakness while simultaneously pumping ETH to pretend it's strong and try to trick people into buying their Ethereum pump and dump.
