The dominance of $BTC is decreasing, in the local charts it can be seen that the price has broken the support of the trend. And this is, overall, a very positive signal for the altcoin market, which confirms the growth of $ETH

This does not mean that bitcoin is going to fall, no. It means that altcoins will show good results

Can we say that the season of #altcoins. has begun?

I think so
