As the question states, i'm wondering how people got access to the ViaBTC Customer acceleration only. When i made an account there was no option anywhere to pay something like a subscription fee.
Do i need to buy a mining contract from them? When googling i can't find anything about it. Does anyone have any experiences regarding this?
They used to have it but apparently they decided to get rid of it (only those who have some remaining, can use it before they clear it out):

IIRC, they used to offer 5 free Customer-Only accelerations for each S9 contracts and each time you mine a single
BTCitcoin they would give another free Customer-Only accelerations (forgot how many).
