Do you still believe in predictions of "experts" about the bitcoin price?

when i see people who only use a chart. and they then draw lines using past price data. i call them trend ANALS (TA) not technical analysts(TA)

you cannot predict a future price by only looking at a past price. it doesnt work that way.
what ends up actually happening is bots stupidly get programmed to repeat the past. thus its not predicting the future. its just created a repeat.

proper technical analysts look at the causes of the past. such as knowing that october 2013 was due to ASICS raising the "acquisition cost" of bitcoin due to hashrate rise asics caused and the higher price of equipment/electric to hash that increase.
ofcourse the HYPE (emotion/speculation) quadrupled the price above the acquisition cost. but then when bad news hit. it corrected down

the reason 2014 bottomed out at no lower than $250 but was higher than 2013'a low of $100. was that the $250 of 2014 was the underlying bottom value of acquisition costs that no one is foolish to sell below.

the 2017 spike was not about hash power. because november2017-march2018 had no change in ASIC tech. the 2017 spike was PURE HYPE of the "segwitx1 locked, segwitx2 rekt" which is what the big bankers were waiting for and contracted paid devs to push through so the devs can release their tranch of funds for meeting their contractual duty. the bankers then went on a big buying round and speculators got all warm and fuzzy that some drama event and code finally got to its november2017 deadline.

ofcourse because "acquisition costs" didnt go up as fast as the speculation. that spike too was corrected down.
which then resulted with prices staying low and near the acquisition costs. which fluctuated above $5.8k due to a few different reasons.
..
in short if you see someone say "price will move because of X prior date did this" they are trend anals
if you see someone talk about the acquisition costs of mining and they actually explain when a spike happens there is nothing backing its cost so expect it to pop and correct. then they are more of the technical analysts.

however even technical analysts that actually look for causes in reality.. cannot predict the precise time. or how high it will go. they can only suggest if a large movement is backed by real costs that people will refuse to sell below. which will hold a price at a new bottom.. or if the acquisitions costs have not increased. then expect it to correct back down to the per hype value(but cant predict when)
