Bitcoin Steady Near $59K; Gains in Altcoins Push Crypto Market Cap to $2T
"As altcoins rise, bitcoin’s market dominance is down to around 57% from near 73% at the beginning of the year."
While Bitcoin price hits the high price of 59K but with a drop of dominance gradually, investors are putting money not only to Bitcoin but also to the altcoins markets.

In the past few years i see that when bitcoin price is increasing then most of the Altcoins price also start increasing. I think this is not happening for investing in Altcoins by investor. This happened because every investors are holding their coins when bitcoin price start rising.
