Let's get back to the topic.
In theory, in traditional stock market, if we invest into two negatively correlated share, the risk are minimized because if for instance; Stock A's price increase, stock B's price will be decreased as both of these are negatively correlated. As a result, investor will realize minimum risk; profit is lower as well. The goal of such investment is to minimize the risk as much as possible. Since the cryptocurrency market is highly volatile, if we choose positively correlated or only one crypto to invest in; the chance is we may lose half or more value of our investment; hence, in theory, negatively correlated can save us from losing the investment in a significant value.
I have got this site providing correlation of different altcoin against bitcoin- https://coinpredictor.io/altcoins
Let's say; Coin A has a positive correlation of 0.89 against BTC price & Coin B has a negative correlation of 0.89 against BTC price.
Are we safe to say investing on both these coins are minimizing the risk; provided that I will have a good research on both these projects to ensure that these are not shitcoins? Ignore the fact that all coins without BTC is a shit (Note for bitcoin enthusiasts).
We cant apply this on several coins but lets say we do correlate with all alt coins in the market.We do base on dominance on here and i believe this is where most people do base on
rather than spotting on several alt that do possibly correlate bitcoins price.
One thing i do follow which is looking on dominance over alts then this is where i do get my basis.
