Yes, this bottom looks like the October one and it is AT LEAST a medium term bottom.
Pull up bitcoinwisdom and look at finex or stamp on a longer timeframe chart (say 6 hours) and zoom out. Look at the volume! Now compare it with the bottom at 275.
If your point is we had MORE buy volume on Oct. 4th at 275, then I agree with you. And look at where we are now. I don't see this as reversal.
A reversal is when you can go to a 30m, 1h, 2h, 4h, 6h, and 12h chart and all see the same thing: rising price on rising volume.
Its possibly a short term reversal. It'll go back down. Here is how $ 275 played out after. . broke down

Based on the October event, we may face a similar bear attack once we reach $250 in 24 hours.
