We have to watch the next moving of bitcoin to decide if it is a bubble or it will continue rise to new high. I recommend using 5D chart. It's perfect timeframe to compare with btc itself 2013 bubble in 1D chart. We have a big rising wedge. Price is up to fast from 800$ to 5000$ and it will have a big correction. Below fibo 0.5 (2500$) will be bust the bubble. But if the price can hold, we can see the huge move up after correction.
