In the last couple months, it would appear the "East" is leading the Bitcoin price: when the "East" is buying (and the chart goes red) price has often proceeded to rise as the "West" plays catch up (and vice versa).
However, unfortunately this pattern appears mostly random in the longer term. So I don't use it for trading at present. If you are looking for another factor of confluence, this *may* be helpful.
... it will be interesting to see how it plays out into the future!
Huobi is based in Asia.
The exchange / user base world changes rapidly in Crypto, so no doubt this will need revision in the future.
