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.
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.
