There are LOTS of warrants that trade freely. It is not unusual at all. I own KTOVW plus several other publicly traded warrants, and have owned many others in the past. All of them were bought separately on the open market and not split out of a "unit" consisting of common + warrants.
The KTOVW warrants, with a long time to run until expiry, offer significantly more leverage (either way) than the common shares.
If I could afford to buy all of them, I would not need to buy any of them and I sure wouldn't be spending time on the message boards!
