If you are a trader then probably you know how the candles move, what's the normal movement and what's not, Probable you know how dangerous BTC chart is, The more up it goes .. the more it crash !
Now you don't see that in 30 minutes or 4 hours frame charts, Every frame gives information for a different range of time
If we don't call it a bubble .. we should call it a correction
So be aware of the coming correction
Cheers
