yeah if you purchased the L7 preorder it was 17000 usd.
I mined well over 35,000 in LTC and doge from it.
Jan 2021 to Aug 2024
According to whatomine : https://whattomine.com/asics/150-bitmain-antminer-l7-9500mh
Having your L7 running from the first of january 2022 until july 2024 (that's as far as they go) would've rendered you : 17429,67 USD if you sold your coins every day, that means if i did the same i would only break even after two years and half of mining.
Here's the google sheet of the breakdown of every day:
