Can i get a good ROI after investing my savings for the upcoming SpaceX?

After deliberating for a while, I decided to make the bold step and commit some of my savings for the SpaceX pre-IPO which will be going life officially on April 21.

After some calculations regarding the numbers and feasible returns, I decided to go for the preSPAX which will mirror it price in a 1:1 valuation.

Currently the preSPAX valuation is $650 with projected price when it's officially live around $1000+

I'm just hoping this gives me a good ROI

Is this a good investment or Just another mistake?
