In my on view bitcoin will definitely take the control of the market because once there is change in value of bitcoin its a most it affect all other coin in the market.
In my opinion, Now I see the price movement of bitcoin is very slow, actually there are some coins that I see price movements start fast. One of them is the altcoin, for that I predict that there is a possibility in the future that altcoins will be able to control the market and beat bitcoin.
Until now bitcoin still controls the market, but I am not sure that bitcoin will forever control the market.
