As you see above, I think we're in wave C of a Expanded Flat (Scenario 1) which wave 1 of it is completed. So wave 3 is being started. So lower dominance is expected. There is another one (Scenario 2) saying descending cycle is completed and new one is started. So again we can expect a lower dominance too. Briefly Altcoins are very suitable due to the chart above and may have more profits for you in the mid-term future.
