I remember getting very, very close to the top 10 sometime back, but got thrown into the 100s just because of a small change in the BTC price which pissed me off. BTC was my sworn enemy for a moment back then.
With predicting BTC price this is absolutely the case. Bitcoin price can change big time within a week, and no one can even tell in what direction it'll go. Once I was among the winners of Bitcasino.io's Bitcoin Predictor challenge, like this ongoing one, but I never thought it happened because I was such an expert. Of course it was pure luck.
this is a contest that involves luck, not knowledge. even if someone has mastery of technical analysis and takes the bitcoin chart and puts a daily candlestick period on the chart, then sees support and resistance and does analysis to predict the monthly price, at the end of the month that person does not will be able to predict what the price of bitcoin will be, the most that person can predict are the possible entry points to buy and place the stop - loss, but there will be no way to say that: " until day Z the price of bitcoin will be 23000 $ ". what we are doing in this contest is just playing with luck, and this is definitely the wonder, because if the person gets this person right, they will be very happy to be so lucky
