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.
