It's going up and down, no need to worry; on the long term, the tendency is very bullish, due to the economic crisis, inflation, and the big qualities of Bitcoin.
The long term impact of bitcoin will be positive ,but we need a good correction now after a bull run we had and it might take some time to see another big rally unless we see some major announcement in the derivatives market about trading bitcoin and the time line in which they are planning to implement,other than that we might see a dull year ending this time around.
