I don't want to sound bearish right now.
But, a reliable indicator is signalling sharp correction in the next 1-2 weeks.
I'm talking about "Dominance by Open Interest".
Right now, Bitcoin OI dominance is at 40% while others (Alts excluding ETH) OI dominance is at 35%.
Historically when Others OI > Bitcoin OI, a local top happens.
Looking at the alts rally, I think this could happen in 1-2 weeks.
This would definitely not be a cycle top, but rather a local top before another major rally leading in Q4.
