And when its price hit US$300 people will sell some of their bitcoin, then the price will be decreased again. There is just a little chance for its price will reach atleast US$500 for next 2 years imo.
All it needs is fresh demand from new buyers. There's no sign of that on the horizon but future developments might bring that. Right now it's just the same old characters batting coins back and forwards. Unless it manages to break out of its current niche it's not going anywhere.
Since its price is going down now, I guess people wont invest their money in bitcoin for now. The better targets to get newcomers are just for people who living in crisis country or those who getting problem with their taxes. In the other side, there are many negative news about bitcoin which it be used to buy drugs, weapons, etc.
And what would people living in countries in crisis do with bitcoin? If you have a crisis you need some safety not gambling on a experimental currency who have lost value the last two years.
People who want to cheat on taxes or buy drugs and weapons are the ones who need a currency like bitcoin. Avoiding the law is the only real benefit of bitcoin.
