Today I found some rise in total coin market cap reached 580+ billion still rising is that the good sign for next big pump. It was in between 500 billion last couple of week today its rising.
Frankly, a total market cap of all altcoins combined is not a definitive factor IMO. Market cap has always been somewhat vague and unreliable indicator.
I don't think that rising market cap will be a cue for the next big pump of BTC. It is more like the crypto market, in general, are getting bigger.
