On what basis do you assume it will fall?
I mean it has not fallen that much yet. I doubt it will go lower that 7000$ now.
There could be many reason to rise and fall.
To Rise:
1. Demand High and less supply.
2.Out of 2.1 million 1.6 million already in market. so remaining is very less.
3.Its decentralized , so no one has control over it.
To fall:
1. So may people can buy in low rate . if price never go down then only few people have these cryptocurrency .
once price will go down many people can invest.
2. More people more popularity.
Add here if i missed something.
You are right, but I think people want to have BTC, how much they can, and put their money on it, but I believe if anyone wants to be rich with cryptocurrencies they should invest on Altcoins, specially on ICOs with high potential, just look at legit ICOs like
gilgameshplatform.com. They are working on an concept that help human being to be rich, all of them!
