What if you invest in yourself ? Or a business you know ? Bitcoin investments dont really exist because bitcoin is so volatile I guess.
You can count altcoins as investments too. Gambling is much better then HYIP though.
What do you mean by invest in yourself? I will prefer to invest rather than to gamble but there are times that I can't think of way to sustain my needs when I'm seeing my investment on a falling line. I'm thinking of trying to go with gambling because most of the time I'm being attracted by those people that are winning good money in gambling.
You may get attracted by looking at the people who are winning regularly in gambling but you cannot expect that you will also get same results in gambling and there will be more chances that you keep on loosing your money regularly as in gambling you cannot have control on your money but if you invest your money in trading then you can control your funds and depending on movement in the price you can take decision of either selling or buying.
