Its been 5 months now, since I joined cryptocurrency ,I've seen many ups and downs in Bitcoin Currency and Altcoins even in those Rank 2 to 100 in Coinmarketcap, but I just want to clarify why every end of the year starts in September then up to December Bitcoin fly high, any fundamental reason why does the value of Bitcoin and other currency go up?
Definitely a myth

well so far since september Bitcoin (and Ethereum's) movement has been nothing but down south. I get worried sometimes but a bg part of me still believes that it will recover itself in a matter of time.
