As the past evidence, it will touch the sky. But if we ll look at the current scenario this year, from aug till now it has gone up nearly 3500 $.
Technically it is overbought and its very clear that before giving a new high it will retract to at least 38% as per Fibonacci (a technical analysis tool). Always remember the golden rule : buy lower and sell higher Investing in bit coin still a very good idea and it may touch very high very soon. But wait for it to retract, come down and that would be the best time to invest. It is my own opinion, plz do your own analysis before investing.
