I think people have a particular fear before investing in bitcoin. I think the biggest worry of many investors before deciding to invest in bitcoin is unstable profit and the big threat from the hacker. So few investors agreed to take the risk to make a profit from bitcoin.
Well aside from bitcoin introduced as having unstable prices, the legality issue of the certain country have a big impact on using and investing into bitcoin. The people of that country will have limited power and control over bitcoin just like trading with other bitcoin users will probably be difficult and lastly, the scammers who are spreading in the world of bitcoin.
