Bitcoin dominance is nearly at a free-fall. Meanwhile TOTAL 2 Marketcap (the total altcoin marketcap without btc) is at its previous all-time high. We may see a very nice rise in altcoins here for some time, especially should BTC Dominance confirm the expected head and shoulders pattern. I think this is likely having exited its channel strongly with a poor attempt at re-testing a re-entry near the bottom of that channel. Though a 2nd re-test is possible.
On the other hand, this may also mean we that are nearing the end of our bull run (within months).
