fast techo counties like china and japan really add more than can do with bitcoin so that we will find more people use it soon

best is prowth by make more new products then buy it then save it then find best time to sell it

you need to have skill and products so that can get moeny and increase it

risk is make real money   , without risk you will get small amount and low profits

price will keep up till 7500$ at the end of 2017 all market signs say that

when you hod gold you can control $ price but you cant divided gold into 10$  so that  bitcoin is solve

if you want to make real money  ads , clicks and video games  not right place because it will give you number by sat like 100 or 1000 so you will work week for 0.5$

my own e reasons

1. limited number of btc

2. security

3. not need any ID
