Critically observing the rate at which bitcoin value is low at this time, I now imagined how low other altcoin will be by now,even with bitcoins superiority. What is your view?
It all depends on Bitcoin. Its capitalization rules the market, and as we see its fall, although critical for other coins, it did not kill the market.
the market itself is never going to die. there will always be a lot of altcoins in it to be traded because people will always want to make profit. and also there will eventually be better altcoins too.
as for depending on bitcoin i have to say it is a false assumption. we have seen before the bitcoin recoveries creates some upward movement in altcoins but it won't lead to much else. they still need to be individually pumped to go back up again. and they can do that without bitcoin while bitcoin rise doesn't guarantee their pumps.
