The previous time BTC made an ATH (end of 2017), it took BTC 3 years to recover from the drop after that ATH. We might see the same again. Since begin 2012 BTC went up average 0.31713% per day. A good daytrader can beat that hands down with less risk and much smaller drawdowns. BTC down 30% since ATH in 6 weeks.
Market cap of BTC shrunk $370 Billion. Somebody has to absorb that loss. Translation: all bitcoin holders together lost $370 Billion since ATH. To go from this level to ATH it took 64 days. Back down to that level took only 33 days. Not really a proof of strenght.
