I think you will come to learn that you are perhaps coming from a standpoint which is not shared by many who frequent this board.
KXL and its peers are not "investments" they are gambles. With gambling most often it comes down to "risk tolerance" and each individual's assessment of the "risk/reward" factor.
Some of our people got into this venture at 4.00 plus but many of us have been around for a while and while the stock is at its year lows we are quite close to break-even.
When it comes to most venture exchange companies I apply the "gambling" strategy totally, that being upon making my stock purchase I ask myself "can I deal with this going totally into the dumper". If I can't then I wouldn't put my risk capital out there.
In terms of "risk ventures" I would place my portfolio percentage at closer to 50 percent rather than 5 percent. To be candid I do this as retirement entertainment and 5 percent just wouldn't be interesting enough.
Sometimes an individual feels like going for the brass ring. I did that during the "hot times" before the recession and it was lots of fun plus allowed me to help my kids get into housing. Then things went bad and we all had to "retrench". Things seem on the upswing so why not get out there and play again.
Bottom line for any of these ventures for any participants is "don't risk anything you can't afford to lose".
