Saving currently isn't really interesting as a normal savings account gets you about 4% interest per year. if you have money that you'll not spend the comming years it can be set at 6-8% each year but the downside is that you can't acces your money for 5 years. Are you be patient with it?
Very few people are that patient when we take into account the low earnings and the long time that you need to be invested, how instable the current world economy is, and the fact that the investment could turn into a scam then I do not consider that to be a good business.
