What happens when a coin is suspended? How long does it take for binance to release from suspension? Especially from conversion.
Coins are listed on exchanges to be traded, so it is normal for them not to be suspended, this may happen for several reasons, some of which are related to liquidity, technical problems, or even legal problems, but this is supposed to be temporary and be resolved quickly so that trading can resume, if coin is suspended on one exchange, such as binance, the problem will be resolved quickly, but if it continues for more than two or three days without an explanation of the reason, it will most likely be delisted soon.
Obviously they are there for a reason but you should rather say that a suspension is normal and can happen at all times as there are now lots of new coins and many of them are shady so in order to save the user and the exchange reputation, they need to do some investigations first and see if they can re-allow the coin again to be traded or not.
We can only wish that it will be resolved quickly because what if not and we still have that coin? It won't hurt that much if we know we will be refunded but I think on most cases it doesn't happen. A few days of suspension might still be normal but if it's longer than a week or two, that would be alarming already. This is why we should be very picky when we invest or trade and much better if we choose only the most established ones.
