Our first FCT Factom (factoids) market is now live thanks to Poloniex.
https://poloniex.com/exchange#btc_fctFor more info on how to use your Factoids follow our guides here:
http://factom.org/howto.
Pay attention when using the command line, read our guides fully at least once before attempting a transaction.
We are working on an easier to use GUI wallet but it is some time away, if unsure, we recommend holding on until its release.
I can verify this is working, just transferred some test FCT to polo. Def takes some terminal-fu to get it from A to B right now but it works. If you aren't comfortable in terminal, i suggest you wait for a GUI.
