That's quite unusual. Maybe it's a visual bug?
What platform are you using for the chat? If you don't mind, what's the name of the coin and at what time did the unusual crash happen? I want to check out using the tradingview platform if the coin is listed there and see if the same thing is displayed over there.
I don't really understand and have no clue about it, what was that one and why in sudden that the RSI line dropped to bottom for a while, though it was a very terrible moment.
This was in Bitget sir. I don't mind saying a coin name which I was holding for a long was "Pi coin'' (was not in spot, but in future trading).
It happened around 12:00 AM my local time (...........Standard Time), which is 6:15 PM GMT (the previous day). Actually, the RSI line dropped sharply at that time (mighty it could be a reason of that?).
For the ref. the coin is only listed on three exchanges. OKX, Bitget and Gate.io as of now.
