I'd appreciate if someone could answer if they also offered it in the past, since I've only used their wallet.

Great job, I never remembered providing such a service, the past few months I've been bombarded by emails. I don't see any reason to use their services anymore, they've completely changed their business plan. On top of that, I don't like their trading fee policy, the maker (the person who places the order) is charged 0.20% and the taker (the one who accepts your order), is charged 0.40%. Most exchanges, such as Binance don't charge that much, while their interface isn't the best I've seen (compared to those I've used, Binanxey, Bitstamp and Kraken).
