I did a similar chart for SPX but couldn't forget my BTC friends.
Timing being the most intriguing part, I searched for some respectable time projections tool. So I applied the Fib Time Zone and overlapped it with the Fib Based Trend Extension tool.
Guys, keep in mind that this is not a trade recommendation, but a time & trend projection. Now, here below is my actual practical view. Also, I think BTC is not going to drop in a straight line, but there will be some insanely abrupt spikes, so don't fall in love with the downside.
