Anyhow, it's just a game of probability, not an exact science. In my chart, 28,189 is BTC's 61.8% fibo retracement. That is expected to give strong support. In case, it will break down, the next base will be at 17,145, BTC’s 78.6% fibo retracement. Indicators like these are useful in stock trading. I am not sure if the same tools are applicable to crypto.
