Well it seems like many people missed this train, let's do math:
The final price was around 400 rep/bitcoin (230 usd)
With 3 bitcoins you own a little more than 1/10,000 of total reps.
Rep will get profit from fees.
In a conservative scenario where each month only 3 billion usd are wagered on this, ( today there are single sport events where more than that is wagered on a single day, i think the total amount wagered worldwide on sportsbooks and prediction markets is around 100 billion/month but who knows, it may be even 500 or 1000 billions.)
Let's take a 1% fee of that, that is 30 million usd.
Distributed into 10,000 parts the result is 3000 usd.
So with 3 bitcoins (690 usd) you had the opportunity to make at least 3000/month without doing anything.
Obviously all this is on the supposed scenario where they deliver and it goes successful after it.
