Well then it seems like it was a good deal. It is in general at the moment very good to buy miners, at least if you believe that bitcoin can recover longterm. If you are lucky and pay the miners in BTC than you can even buy back the BTC with fiat in a few days/weeks for a discount.
Actually, no one knows if the price of Bitcoin will stay stable at $20k or if it will recover in the long term but there is a strong support at $20k so there is a big possibility after a few months it will increase. About the discount deal maybe November is a good time to buy(BlackFriday and CyberMonday)?
Canaan also has many discounts their units are very cheap nowadays look here https://shop.canaan.io/products/ It would be also a good deal.
