I know I am not pro or old here but I know little bit. I was saying that Bitcoin is just had always proven good start in December month and in first Quarter of New year and If history repeats than
December isn't always a good month for cryptocurrencies,
the thing about history is.. everyone can see it and react to it to "never happen again"
meaning if traders see a pattern that a high happens at a certain time.. eventually enough traders plan to hedge that by selling in that historic suggested time. which then ends up that due to mass sells. the next time of that suggestion sees less highs due to sells.
a pattern is only a pattern until to many people use pattern recognition trade bots to trade against the pattern
