OP I cant get it, what type of suspension you are talking about some sort of delisting or temporary unavailability of a pair, it depends on what you mean by suspension of trade in any pair or coin if it's due to the platform they'll fix it within the deadline they gave in the announcement and you can follow their latest developments to stay updated, if there's something wrong with the Coin itself then the suspension depends on the scale of victims.

Suspension may vary from situation to situation but the delisting sort of cases are not the same, those who are delisted probably don't get enough trading volume and market interest, exchanges used to delist such dead coins but they provide a proper delisting timeline to avoid the fund's loss issues for the users.
