Today is ETH merge and your point doesn't look like it's happening, all top altcoins are down, why would you think of such when September is one of the most bearish months of all.
supporting this for the common story , market shows bad movement every september so this is not common to expect a good increase this month or even in the next , what we need to see? is that November and December in which mostly the reason why expectations happens that time.
People are thinking too far about the bullish market while the trend was still showing if we are still in the bearish trend. I didn't even think altcoins will be going parabolic. it seems like that OP needs to lower its expectation.
The bullish trend will not come this year. it will be coming in the next year. i think this gonna be real for sure.
