That day they delisted a number of other tokens that also dumped so hard. The coins including waltonchain, Bitshares, PERL. I am not sure if the delisting comes at a time when Binance is under fire from the regulators, or this is just their routine.
I am actually surprised that TORN was still trading on the exchange after all this time.
Binance still plays a major part in the cryptocurrency scene, so the token delisting will surely affect the market. I believe due to regulatory pressure, even though it is not a direct way to this particular token, they feel pressured to delist such kind of token. Not to mention this particular platform is sanctioned and you know the story. So, it is likely they did it for purposes.
Regarding the token itself, surely the liquidity will not be like before, but if there are still an usecases within the platform, I'm sure the token will hold on.
