I agreed that bitcoin controls the crypto market, a dominance rate of almost 90% regularly should be a concerned; and to me, this has become a permanent situations. I think that some of the major altcoins should be promoted to the extent that btc control may be separated, and be traded just like the Stock, and foreign exchange market are been traded. Bitcoin makes makes many altcoins rally ineffective and some times shorten the progress of a rally. In fact, every altcoins rally depends largely on the btc movements.
