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.
Different people like different types of investment, just like a thousand readers have a thousand Hamlet. And I prefer a steady investment.
You are right, it depends on everyone's character, adventurous choice of trading or gambling investment, if you worry about losing their own money, people are more suitable for sound investment.
