Bitcoin was once dominant in the crypto market being pioneer of crypto currencies.Then it started to lose its dominance gradually due to the entrance of hundreds of new coins.
Bitcoin's dominance was at its lowest at 36.1 percent.
But now, once again bitcoin's market share has reached high to 57.09 percent which shows that people have lost faith in most of the shit coins and find only bitcoin to be the safe haven.

This was quite obvious too because Bitcoin is the first cryptocurrency to be launched and it has maintained its prime position since then. So if any new investor thinks of entering the market, he will start through Bitcoin most probably. People have earned huge profits from Bitcoin which causes them to stick to it, thus addition to its market share.
