I think nobody can't accurately tell if it is the right time to invest now. Ofc the price is 65% down compared to last december but that doesn't mean we could even go lower.
I think the best way is to buy in steps, which means buy 10% of your total invest now at $7k, then again in a week or two and then again and again. You will have an average value you can't really be angry about missing the right spot.
