one thing for sure we are getting less eth per Mh
That only affects people that mine and hodl eth.
If you mine eth and convert to fiat and btc you are better off.
I have zero faith in eth for any purpose other than to mine it and convert it into fiat and btc.
So the London fork increased my earnings.
Those that think eth is worth holding are not as well off.
For the vast majority of home miners, converting to BTC makes no sense. Ever since Wall Street got involved, BTC is a rich mans game designed to preserve wealth, not make gains. Too may good promising projects out there with better upside. Even if BTC goes to 1M, percentage wise it won't make you rich, unless you already are.
Yes it is true that why it is good to follow BTC dominance why because : when btc dominance going up it is better keep in btc when dominance changes trend to down it is time switch to alt coins where you can make more % than btc does.
