It is a fact that bitcoin price is under-performing since Feb.
What caused it? Will it continue or turn around? What would cause such turn around?
Instead of examining these points, you attack the source, as usual, as if you want everyone to be silent about and if everyone stays silent it would get better somehow.
It could get better, but only if alts get smashed soon, otherwise we would bleed down to maybe 32-35% and then the situation can become unstable (multi-polar).

My btc % is much higher than 40% market weighting, so I would be not be a happy camper if btc further declines in dominance and/or in price, yet I have no plans to sell.
Why? Because I believe that we might turn around at some point, could be soon or by the year end.
I never sold any btc for alts, but their proportion in my portfolio (bought using fiat) has arisen in this cycle quite significantly for a simple reason-a gigantic outperformance (so far).
Not naming any names since it is OT here.
I don't chase and try to buy low or very low. All my alt buys were done before the end of 2020, most either in 2019 or even earlier.
In 2021 I am only stacking btc sats via mining and small size random buys and slowly selling some alts, but even so, each sell was not at the highs, admittedly, so I slowed those sells down for time being.

Are you going to tell me that selling alts and buying btc is somehow impure (like you told Phil)?
What a wierd suggestion, pal!
