Polkadot indicator? Data shows Ethereum price follows it to the DOT
Furthermore, DOT's price action seems to be somehow anticipating Ether's by 15 minutes to 4 hours. Both DOT and Cosmos (ATOM) anticipated the Ether rally on Sept. 9 and the subsequent descent on the next day.
During this time DOT began a strong rally two hours ahead of Ether, and it also initiated its trend reversal earlier than Ether. The same can be said for the many false positives and opposing movements that happened exclusively to DOT that were not replicated by Ether.
