i would like to recommend to invest on alts which has no many market atm but has a great future project.
It will 10x - 20x your money in 1-2 years.
such as : ETN, NAGA, Indahash and any other big project
There isn't any 6 months payback project you know?
I mean I was asking if I keep 100 ETN will it give me more coins as reward every month ? like a savings account in bank which gives you interest on the money in bank account
