Every investment is a gamble. Pure gambling is just raw luck, so if I do it I only do it for fun and in small amounts. So I would prefeer to invest in something that I think is undervalued because of reasons, like a solid project such as Maidsafe, which I think is severely undervalued at the moment.
There are few alts investing money at, but few I think are undervalued, which can lead to good profit in the future.
