From the Historical charts i don't think there would be bear market so far, all i see is a positive trend which would like touches back $19k but within 31st December to 10th of January we could see it at $20k to $21k.
Well, that is if the history repeats itself but what if not? There's still a possibility that prices can move randomly. BTC is now in green but the increase were only small so I don't think this can be said that we are now going for a bull run and the bear market will finally end though this increase can continue till we touch $19k, and the other two values that you listed above. They are only small so they are pretty possible to get. What about now @fennic. The price of $16k per BTC is still a best buy imo.
Don't expect too much about the bottom because the price of BTC can still rise even without it. Buying alts is also fine as long as it was a nice alts, and not a junk one.
