For bitcoin gold, the blockchain snapshot has already taken place, so it should be safe. I am more concerned about Segwit2x hard fork in mid-november.

Bitrated is a multisig escrow platform allowing safe trade between parties. I intend to use it for a trade involving locking a significant number of bitcoins for several months in escrow. Problem is, once the trade is completed the party claiming the bitcoins will likely receive coins from one side of the fork only, and potentially lose a lot of value.
