I expected normally that during the periods of end of year's festivity there should be a rise in Bitcoin price that is sustained for let's say 5 months after with little fluctuations but it's not been so.
Bitcoin and Crypto-currency generally does not have a rule book or text book to how the price flows. It's all about the happenings of the market in the present time, we all are entitled to our speculations or price foresight, and many of us has even planned ourselves towards like like when to buy Bitcoin and when to sell.
It's calculated risks when you have good source to atleast back your speculations but it's not a guarantee. That's just the market. If you also go back into history you would see that there are some years that would be in contradiction to your notions .
