You and 100 people get 50 million dollars now, but in 10 years you have to volunteer your body to be cryogenically frozen.

The process for being cryogenically frozen is equal to whatever company has the most advanced process now. All 100 people involved have to give themselves up for science. After 5 years of being cryogenically frozen, 2 people will be chosen at random to be revived. This repeats every 5 years and no sooner. If both people are successfully revived, that same process is used for the remaining people of the test, although the results are not guaranteed. The company has infinite money and can't go bankrupt. If you were successfully revived, you get another 100 million dollars for your service.
