Bitcoin can reach 3000 USD in a year ?
No it cannot that would be very high, and bitcoin cant reached that price within a year only. It needs 2 or 3 years before it gets to the price wanted by some bitcoin users. Well gonna see more and big improvements in bitcoin after 2 years and it may lead to 5000$ price.
I agree. It can not grow so fast, it takes more time. The price can not constantly go up and during this year there will still be small reductions that will not allow such growth.
