Ignoring the margin call fueled spike to 2500, the real top of the rise (that people were placing real buy and sell orders at), was at 2350 sats.
For the move form 1401 to 2354, the .618 fib level is at 1765. Thats right at our current low. This is a good level for the bottom to occur, so I would start putting money in if I had it (and will put money in once I get more).
1625 is the 76.4% retracement level, so thats the other main target at this point.
It should bottom between 1600 and 1800.
