I think the crypto market has reached a size where it doesn't matter if Tether fails. I'm very sure that it can absorb the shock. If Tether fails, it would cause a dip in the short term, but Bitcoin will shrug it off. Bitcoin and other cryptos do not need Tether to survive, so I don't think its failure would have much effect.
