If you want to make revenue from your investment. Think about it.
If your website or blog have revenue $5 clearly.
Doing more with 20 blog and you get $100 a month.
Simple investment I think.
Go to domain panel. Search your name.
Take buy 20 domain and take one big hosting.
Sample.
one domain is $10
20 domain is $200
one big hoting is $100 a year
Full your money investment is $300 a year.
If you get $100 from this 20 domain.
So you get $2000 revenue

And get the fresh money $2000-$300= $1700 in year.
I think you must divide your time in manage your domain.
So you will know your investment business.
