I have the opportunity to upgrade my Saturn for $3500 and really not sure what to do. It is already pumping 400G/H/s which isn't bad for my first miner. If money wasn't an issue I'd probably just go ahead and do it.
Has anyone else upgraded their units with their upgrade packages or just kept the same?
Other then buying a new Jupiter, upgrading a Saturn order seems like the most cost-effective way to increase your hashrate. No one knows what the difficulty will look like in Sept/Oct through. There's going to be raw Avalon chips, Bitfury, etc plus possibly dark projects hitting the network by then. Anyway we have until august to decide.
Well you can go here for a reference. Basic idea is if the network increases on average of 20% in difficulty then that is a 12 day difficulty run.
Now that is assuming the network difficulty is at 64 million as an increase of 20% would be by September. However the Avalon tab is updated with present and future expected network difficulty. The average past increase of the network difficulty is 17.4%.
Consider that other miners are putting hardware online by September/October. By then 20% increase seems low we may see a 30% increase for a few rounds of 10 day runs perhaps normalizing in December.
Please remember that this is speculation on known facts. This exercise is an attempt to manage risk.
