usually an exchange will remove a coin or token,
because the coin or token didn't have a good volume and less trading activity
and thats very reasonable for the exchange to remove it,,
this is to make the exchange stable and always listed a crypto with good volume,, thats my opinion
expect the best exchange on that planet ^
original quote from warden : .. even death coins are traded. ^^
unsure why an exchange should delist some coin ..
the 3 Dollar monthly server fee for the workload are peanuts..
and until this is covered i see no problems
