Have you compared the fluctuations of ETH against other top currencies? What I'm getting at is: perhaps BTC has already started its own life, or rather, is preparing for some big plans.

$ETH now you have seen how Bitcoin destroys Ethereum and takes all the money for itself. Bitcoin falls by 1%, Ethereum by 2%, Bitcoin rises by 2%, Ethereum by 1%. And again Bitcoin falls by 1% while Ethereum falls by 2-2.5% and here we are at 3200-2900🤦‍♂️
