I am tired of changing the small value tokens to BNB but thanks to the Binance team for this option to clear the dust from the trading balance on exchanges. The reputable and established exchanges can change the rules for any project, I prefer quality over quantity.
im not really familiar with those coins but if they will delist those coins, it means they have good reasons to do so. better clean their list and remove those crappy ones.
unlike other exchanges, they have long list of dead coins but still in their list. should do the cleaning every once in a while to keep their lineup neat with quality projects. i guess this action should be done by every exchange so we will only see active coins in trading.
Finally, an abandoned project called tierion will be delisted from binance. All of the social channels were not active. The volume could not become the reason why binance will delist it.
The developers have gone with all of the money raised during the crowdsale.
No update on tg channel, tg chat and all of groups were getting abandoned.
i believe the major reason is the commitment of the team to the project. because if you will check their trading volume, they are not by any means the lowest.
so getting a snapshot from OP's link, the possible reasons -
now up to you how you will assess their respective situation here
