3 Different possibilities for a BITCOIN bottom/reversal.

Just going off some trend lines came up with these 3 different targets for a reversal. The green triangles labeled "possible buy zone?" would only be good if they follow the specific downtrend target , the plan is to purchase BITCOIN towards the end of the bottom so you don't miss out much when its reversing. There is no order in these targets for reversal for which only time will tell. Let me know what you guys/gals think!

ps. my 1st chart by the way
