With many altcoins appearing overbought in relation to Bitcoin (BTC), as evidenced by the Relative Strength Index (RSI) across multiple timeframes and lengths, there is a strong possibility of a reversion to the mean (a BTC Dominance bounce up from around the physiological 50% level).
Most often it is argued to not use the RSI as an oversold/overbought indicator but I have always found it very useful when used in confluence with many lengths and timeframes, as a mean reversion indicator. (as seen in this chart)
Although I don't have a predefined profit target or stop-loss in this scenario, the chart suggests a potential reversion to the mean for BTC gaining strength over the rest of the cryptocurrencies.
