I have no problems if that is your style however the bitcoin dominance is important to me because that indicates where we are in the market cycle, altcoins are now moving at a higher speed than bitcoin which means that speculators are now in control of the market, this has the consequence of having an increase in the volatility of bitcoin and altcoins and that now the market is behaving a little bit more irrational, which is exactly what we are seeing with the flash crash we saw a few days ago.
Probably you are right but you cannot predict the future just by tracking where the money flow into. I mean bitcoin dominance may get you some idea of where the new investors are heading to. But, if you take one decisions when bitcoin dominance is around 50% and when you take another decision when bitcoin dominance will be 60%, both do not need to be right as at any time future investors might change their investment options. So, not taking any financial decisions based on one or two factors is highly recommended.
As you may guess I cannot predict the future with this, it is just a way to use one indicator and try to understand more clearly what it is happening with the market, if there was a single indicator that could predict what the market was going to do someone would have found it by now, but then as everyone began using such indicator it will begin to lose its edge as everyone begins to move in the same way which is why I do not have a problem with other people having a different vision of the market.
