there are no 'natural' trends.
there are no 'natural' market cycles
what occurs is some stupid trend anal guy see's 2013's rise.. sees late 2017 rise and shouts out "every 4 years theres a cycle"
what not been told is the 2013 rise was due to the invention of asics
what not been told is the 2017 rise was due to the invention of futures options
2 separate events, 2 events not tied to each other, 2 events that wont repeat
but now. because of trend anals. people start programming their bots that in 2021 expect another big event. (facepalm)
the foolish part is. then a group of bots plans to buy during 2017-2021 with the hope to exit at the preached facepalm date
theres also a group that think due to halvening of 2012 and 2016 they need to buy before 2020.
this causes bot programmers to set thousands of bots to buy early. to get best prices
thus causing rampant price rises.
not due to any actual natural proved trends. but simply reactions of hearing that someone preached something wil happen.
its like self fulfilling prophecy or better known as pump and dumps.
announce something will happen that wont happen if you kept mouth shut. but you cause it to happen just because you opened your mouth,
so here is a simple lesson.
if you think you can predict the future. thousands of others have thought the same thing and set their bots to do so. so by the time you want to act on your plan. others already have.. and you end up too late.
same goes for price dips
the 2014 dip and 2018 dip was not "trend" but was mtgox and a mix of futures sell off and next gen asic where old gen were sold off causing mining to get cheaper thus pools selling at less and still profiting.
this does not mean there is a natural "winter dip" as the events are unrelated and next winter wont occur again. but now bots have been programmed to foolishly think there would be a winter dip and so they will do things before winter,
so again if your planning on a winter dip. thousands already have and so they will react before winter to effectively maybe cause a autumn dip before the preached winter dip.
so here is a simple lesson.
if you think you can predict the future. thousands of others have thought the same thing and set their bots to do so. so by the time you want to act on your plan. others already have.. and you end up too late.
you CANNOT predict the future. because by the time you think you know. everyone knows and everyone has planned to act before it
trend anals are not predictors. they are pump and dump preachers. they say something will happen at Z so that people react and try to get in early at Y so that the preacher can get in at X and get out at Z. leaving anyone hoping to see Z as those left too late holding the bag
Your analysis sucks. Both 2013 and 2017 spikes were 100% due to halvings. Most coins for sale are newly mined, which is why halving this supply has such a dramatic impact. It doesn't go up smoothly because that's not how this market works - it way overshoots, overcorrect then settles back down to a price 10x+ what it was before the previous halving. Then the whole process repeats.
Everything you mention, asics, mt gox, futures, icos, is all just blah blah blah coincidental bullshit events people use to try to understand what is a naturally occuring event that was purposefully built into bitcoin. And it works, exactly as intended. The real reason people lose money is they don't want to use what they feel as "real" money to buy it and wait. They want to make free bitcoin doing short term trading, which is nothing more than gambling.
The song lyric "stealin' when I should have been buying" comes to mind.
