Will not come yet altcoin bull run season we have to wait for 2020 and maybe after some months we can have it and also new ATH for altcoins and bitcoin dominance is really high but this is what we need at this time and bitcoin is most used when trade altcoins.
I'm also hoping that 2020 will bring a good season for crypto market not just for altcoin only. If there is good things to happen next year aside from Bitcoin halving then we might see the altcoin season, I'm also expecting that new investors will be involve in crypto space and help the market to grow.
