I dont care much about this recent dip, maybe it could be considered as a crash too, dont forget that bitcoin came from 20k to less than 11k in just three days, that is more than a 45 percent.
Iota hasn't dropped that much, and it went from $5 each to less than $3,6, there were some altcoins that dropped much more than IOTA, just like Cardano, who was at $0,56 and it dropped to $0,28 in a few hours.
Just consider this a big opportunity to re-stock your portfolio of new altcoins at a discounted price, i am doing it so.
And the top 50? i dont think that there are 50 altcoins that are going to suffer that much.
Seems like IOTA and EOS are in pole position
