well, i wouldn't put gambling in the same group as the rest, that's not investment it's just to try your luck :)
just do it under the motto: "invest only the amount you are willing to lose", every investment can make profit or can be a lose depends on many factors and right now, i don't see anything "shockingly amazing" to worth to invest.
Id say to watch the market and news within a month just be have some more parameters to decide
I probably was not clear enough when I said investing into gambling websites. I do not actually gamble but invest into websites providing gambling services. Most of them offer this opportunity and provide nice interest in exchange for these investments. The key is just to select reliable websites which will not vanish in a week.
