I can answer this since i was the one who brought up the question.
There is a debate on whether bitcoin core (what you own as bitcoin today) will continue as is or if a bitcoin competitor (called bitcoin unlimited) will be allowed to exist in parallel to existing bitcoin core.
Both Bitcoin Core and Bitcoin Unlimited will be called bitcoin, but essentially it's two different currencies. Unlimited will allow for larger transactions to pass through its blockchain, this is the biggest (if not only) differentiator between the two coins. Without the ability for larger transactions people fear that the existing bitcoin (core) blockchain will end up having long wait times and higher fees to complete a transaction.
It's silliness, if you ask me, but it's a real debate and the people that do the mining get to essentially vote on which type of bitcoin prevails - core or unlimited.
I asked the question because if Freebitco.in is now a holder of our deposits I'd like to know how they will handle our bitcoin (core) deposits if bitcoin unlimited becomes the "winner" of this debate.
There are a lot of Bitcoin Core vs. Bitcoin Unlimited discussions going on in this Forum right now. I encourage you to do some reading on the Bitcoin Discussion page.
