The price of bitcoin is really unpredictable, sometimes it pump very hard and seems like it will never go down but this time it drops so bad and no one can help to prevent this sudden price change. But even if a lot of fluctuations happens in bitcoin I'm still confident that it is a good investment and that in couple of tears it will appreciate and provide high return on investment.

Are you surprised that in the diagram the bitcoin rate is shown in a straight line, which has never happened before? So that it can be represented as a straight line, it can be influenced by several contradictory factors. However, I think for a long time such a straight line will not last. Bitcoin is too volatile and direct in price for him is too much a rarity.
