If Bitcoins aren't 100K in 10 years I'll be too depressed to do anything with my life. It's pretty much my only chance at early retirement. Also my only chance to hope that when im old I will have money because I think society is going to collapse and the state will not be able to pay pensioners.
If you want to retire in 10 years, you need to buy about 20 bitcoins at least to have a comfortable retirement life. There is a thread about how many bitcoin you need when you retire.
It wil also depend on how much the bitcoin will be worth in 10 years.
Hopefully 5 times higher as it is right now
