Bitcoin- Genuine reversal or bull trap?

Yesterday was a crazy day for BTC, with the price rising strongly about 15% (also stopping me out from my short trade) and now the big question is: Is this a genuine resumption to the long-term uptrend or just a bull trap.
Looking at the chart we can see that 35k is marked by 2 long-tailed daily candles indicating buying power and also there is the possibility of a double bottom. On the other hand, 45k is very strong resistance with price reversing from there from the beginning of the year.
Although I don't rule out a reversal, what I would like to see is a higher low around 40k and a break above 45k for confirmation.
Till then, I sit on the bench and wait for further price development.
