1. How many ASICs should i begin with to generate minimum revenue?
2. Which ASIC is the best to buy?
3. How much approximately can I earn with 1 ASIC (lets say with 1 spoondoolies SP20 jackson)?
4. How many ASIC can I run on 1 computer?
all response are highly appreciated. Thanks
1. There will not be any revenue... Unless you go full "industrial" scale.
2. You should start with a cheap ASIC to learn more about mining - and then you will decide to give up mining.
3. Same as 1.
4. If you are using USB ASIC, then I think the limit will be (127- number of USB hubs), which should give you about 70-80 devices.
I suggest for OP he either starts with a sidehack stick to get used to mining or picks up an s3 to get used to more standard miners.
