Bitcoin dominance at this moment is really low compared on last year and other fork it have. But, that's happen because its popularity and demand increase as it hit 20,000$ last year. In my opinion thats the All-time high of bitcoin. It is normal to decrease the value of it. i also expect the down trend of bitcoin as of this month but in other-hand I am hoping to increase the price up to 50% to 60% of its lost this coming summer.
