You can't mine any SHA256 with the X3, the X3 is only for Cryptonight type of coins. This ASIC was profitable back in the day when you could mine XMR with it. However after they forked you can only mine low cap coins.
See this link,

So according to the graph unless you got free power its not worth mining at all. You make a little over 2 quarters a day mining some low cap coin which value can fall further any day now.

Any of the handfull of sha256 altcoins. Aside from a lottery miner it is highly under powered for mining Bitcoin.
