Yes, it's serious. A word of explanation: a paused investment will just be "frozen" - it will retain it's exact value, but will not participate in the bankroll and profits. An investor could still close the investment and cash out anytime.

I think this is the only reasonable way to run competitions where we share profits with the players (like: 50% of site profits goes to the prize pool), unless anyone has any other idea?

Cheers,
