Today's Coinbase (COIN) listing is likely to remain a focal point, dictating Bitcoin and altcoin price behaviour in the short term. The monthly Relative Strength Index (RSI) indicator, cited by the analyst behind the common stock-to-flow price model for Bitcoin, shows that the current reading of above 92 is high, but falls short of the 95 levels reached in the previous bull markets of 2017, 2013, and 2011.
