I rented SEGAHASH01 (SCRYPT 4.00 MH/S) for 48 hours, will report back how it's going!
edit: in the first half hour, I experienced a bunch of weird dips in hashrate, I hope it won't continue
edit2: I just got a message from senuketo (40 minutes in) that his rig broke down and he moved me to a 4.5Mh rig instead of the 4.0Mh. He also explained that the API is not set up correctly and that's the reason for the dips in the leaserig ui. I'll monitor the pool hashrates and report back
final edit: amazing service, Senuketo overdelivered to the max, I got +0.5Mh/s to start with, he even wrote to me when I changed the worker vardiff and the hashrate went down a bit. I'll lease from him again very soon! Thanks!
