Try doing affiliate marketing, learn and earn. Try out different ventures around, investment on a site might be risky if you do not know the niche well. Research around what goes well these days, and make a wise investment or it might run out easily just like water.
either invest it, or have fun with it. maybe a nice new sports car, or buy a business which gives you a regular monthly salery with not much work involved. yo could buy a nice business with that sort of money.
Start with SEOBOOK for $79 Develop a solid business plan/strategy before you spend any more. Come up with 3 - 5 ideas that you believe will return their investment back to you within say 12 months on a fairly conservative estimate/projection. For saving/investing, I've recently discovered Prosper.com which is like an eBay for loans. It lets you lend money to others and pick the rate. I've had no trouble picking up 10 - 15% interest on fairly solid credit graded homeowners with verified bank accounts. Stick to people with low DTI (Debt To Income Ratio). Of course there is always a chance of default, but Prosper provides 2 specific things to help with that. First, you have historical stats for their market. For credit grade AA, A, B verified home owners, the default rate is almost ZERO. 2nd in the standing orders, you can specify the minimum rate of interest you want (say 10%) and then select the credit grades you want. They then calculate the Experian average default rates and adjust the interest rate for each credit grade to ensure that you receive a 10% minimum return after defaults. Of course that only works if you spread the risk across a lot of loans, but with the standing orders, you could bid as low as $50 towards each loan that qualifies and let the system bid and secure loans for you in an automated manner up to the amount you have available to lend. I was very skeptical at first, but I'm completely sold on it now. I've been allotting $50 - 100/wk to lend for the last few weeks and am very pleased so far. I'm securing some solid loans in the 15 - 17% interest range.
Invest the money. Europe's newest country Montenegro is a beatiful country by the seaside. Very soon people from Emirates and other very rich people are going to invest there so if you would just buy a peace of land and resell it after a year you would be rich. The price for the land is 3 times more expensive now then it was last year. Or you could invest in stocks there and get almost the same profit.
heh .. Buy yourself a good meal, spend some good money on your parents / kids / wife. Take a vacation. Go las Vegas .. Make 100k from what you left, if you lost them all, restart, rinse, wash, and try again. LOL.
Gold, silver, swiss franc, japanese yen. Whatever you do, remember that US dollar may be worthless in 3 years, so you don't want any US stocks, bonds, or savings accounts
