Using fib extension targets are 80.5 and 85.5 and +++. Of course you need to keep an eye on BTC before opening any position on altcoins. I think green scenario has a higher chance (it leads to a beautiful inverse head and shoulders). I have buy orders at 64.5 and also 58.5 (futures is a bit risky now, so I will stick to spot trading! Cheers!
ps: yellow boxes are monthly and weekly pivots!
