Bitcoin's bull run doesn't depend on anything, especially altcoins.
I think Bitcoin price that rose from $60K to $100K can't be said just a normal volatility...
The bull run is already confirmed, but $100K wasn't the peak because the last few cycle, the peak happened a year after halving event in Q4.
Some altcoins have seen huge bumps such as SOL and XRP to name a few.
Yep, most of cryptocurrency are rising, but this is not altcoin season because in altcoin season, Bitcoin price drop while altcoins price rise.
