Yes, in fact, this is the root of the issue in the other thread going at this moment.The models do optimization only to USD value of the account.
But the same principles could be used to optimize to BTC value. The trades would be different. Conceivably, we have a USD optimizing model and a BTC optimizing model. Everyone could select between these based on preference.
As for dominance index, may I request what would be ideal to see? Would it be an index such as you can find on other sites, weighing market cap? Or would it be a prediction of how dominance index will change?
