The very first investment I clearly remember was $100 into a new PTC site, when I turned 19 years old my aunt gave me this money as gift, but investing in a new PTC business was a bad choice, I end up in couple months closing the PTC site and losing another $40, because I paid all members before closing.
After that I built a blog, bought fresh domain .com and cheap web hosting for less than $50, in about 3-4 months that small blog start generate each month little over $100 per month and from there I knew I need lot more blogs, and almost 2 years later I start earning $1500-$2000 per month, finally things started to move towards great success and after that I built this forum. I suggest you guys do the same, have patience, work hard and success will come in a couple of years.
