Such "opportunities of a lifetime" are only valid when you have a functioning global economy. But the smoke and mirrors of the fiat system is now coming undone.
I see one of two things happening tomorrow:
1. The Fed announces that they are flooding more money in the system. This will be enough to goose the stock markets for a few weeks. Or a few days. Or maybe an hour. In any case, you'll have the chance to sell over $4.
2. The Fed does nothing. And your "opportunity of a lifetime" is closer to $2.56 than $3.56.
Do yourself a favor and read some Zero Hedge. Even if you don't agree, it's good to acquaint yourself with what a growing number of people really believe is going down.
