Depends on how each individual institution handles it: Some exchanges and banks to trace lets say the last 20 hops, and if these are OK, then they accept the coin. I know also about institutions which trace ALL hops, meaning: At their desk you cant ever sell a coin that has been in the dark only one day since its existance. Most have a relaxed approach, like "if the coin wasnt in dirty hands for the last 5 or 6, its OK for us"
