The "price performance" here is because LTX were on their Shooting Star platform (much like coinbase's MoonBase, I assume) where they select few token to have special IEO. Doesn't necessarily means being delisted like the case of low trading volume like what usually happens with other projects. LTX price just didn't perform like how they predicted (which... the price dive down themselves is not a secret to this community). With AMA coming to us soon and MVP around the corner, price should stabilize.
Hope the AMA clears some questions about the project. Being delisted is almost never a good thing for public. Maybe there are some other reasons behind it that we don't know.
Hmm... Did you read the article given by the post? Or what Wedosgibas and I said? The explanation is exactly there, if you put some effort to read. The reason was because LTX were on bitmart through shootingstar platform, they require projects within this platform to achieve certain price. And because LTX went down, this condition was not met. Thus, delisted. Simple as that. There were no negative news or reason behind this delisting.
