the way i see it there's far more downside risk than upside atm, worst comes to worse I miss bottom and pay a few percent more than ideal. Worst case you try and time it and end up loosing your shirt.
I see it hitting $10 in the next couple of months and then staying between there and $20 for a few months during the despair stage. There will be ample time to buy later, the risk lies in panic buying.
Sorry, you missed the bottom already.
