I haven't just cited it! I said I saw a screenshot. I don't have a date or whatever, but if someone has a date then I can download the ticks from that day and check it out.
Without a date I can't compare the short interest at Kraken to e.g. the $100,000,000 OI in USD-settled USDT futures at FTX today.
If something that weird (a USDT price spike to $1000) really did happen, somehow nobody noticed and nobody was affected, in spite of millions of dollars of daily trades in that market at that time
It's probably a glitch in Kraken's historical chart
Many people noticed. It’s not a big deal because the market is mostly wash trading.
It’s not a glitch. How you can say it’s “probably” a glitch is beyond me, you have zero evidence to support that. There have been other instances of Tether spiking well above $1, that is simply the most egregious.
Can you find any contemporary report of that May 11, 2019 USDT price spike incident at all? Because, if 'many people noticed' it, as you claim, then that should be easy
But I'll tell you now, to save you time: there are no such reports, because it did not happen.
I don't know anything about 'other instances', I only assume that spike on the Kraken chart that you linked to must be a glitch, because I found zero corroborating evidence for it. As you yourself have implied, such an insane price spike would have been a significant incident so it could hardly have gone unnoticed.
Your arguments would be more persuasive if you based them on facts.
