So for little bit of interest you are risking your hard earned money there? It is quite risky to use any web wallets to store bitcoins and wallet freebitco.in have also doesn't look like real web wallet. They might be storing all bitcoins from users in cold wallet but there is no guarantee that your bitcoin will be secure there because you have to trust a third person.

Anyway it looks like users will get coins in both chains in case of fork, that is good news.
