Remember that most altcoins are following bitcoin pattern, if bitcoin goes down, a lot of altcoins will follow the same trend too.
It happened on June too, only a "few" altcoins were in green numbers after the great dump from $3000 to $2000 in just a few hours.
And as BTC is simply long overdue for a correction, I suspect BTC's dominance could fall within a matter of weeks, if not days..
That is the same question that i have been having in my mind for the last few days, should i keep holding or not?

That is something that i have been thinking a lot..
but there aren't many alternatives, if you sell, you need to move to alts, it is simple as that, so it is the same.
