what you can get from seeing a bicycle Dinamo that produces 6v ~ 12v to switch on 5v sized lamps
what if Dinamo u can to magnification

other in your hand
2mil is not a small value even I do not have it,
if you really love BTC why not you make ICO for your exchange platform
through exchange plaform there are many things you can list.
among them mining - exchange paltform needs this for daily transactions.
most of them provide their own mining pool to ensure they can deal in the best system for their customers.
In addition to taking an example from Biz-z, "Vote coin",
I suggest you use skrill or paypal from alipay because there are many traders have it and it's easy for you to manage it,
so if you agree then consult those who are experts because I have no experience in this matter.
but if you are lazy to manage the exchange platform
just looking at mining as the best way to expand your investment then I have no idea how to share it,
since there are many resources you can get to develop a mining-based investment structure.
if u agree to build your exchange platform - invest profolio dont forget to list free my TokenGo because I give high appreciation to my TokenGo.
