Invest some cash into BTC, BTC price rising to $10,000, me having few millions. The real cornerstone of that plan is BTC worthing $10,000 but time will tell if it can actually reach that level 
I am also aiming for 10k price levels. But, I just keep on buying bitcoins only on monthly basis. May be I require 100k price levels to become rich with the number of bitcoins I will have.
