their twitter says not to send MSC now, and the address is removed, i would expect your coins to be returned if you send MSC now
but I know nothing, just assuming
Twitter says :
"The sale is still ongoing, please send bitcoins to the BTC address found at
http://www.safecoin.io . Please do not send MSC to
this address."
There were (are) 2 separate addresses, one for BTC and one for MSC.
I think that the MSC aadress should still work. They are just trying to discourage people from sending MSC because BTC is much more liquid and thus more valuable right now.
