Is it worth it? I wonder if I would ever make any money...
no it isn't, you need a little farm ata least to do somethign at this point, or bitcoin need to skyrocket to 1k to be slightly worth it
if with the money of the s3, you have bought some btc(probably less than one but still..) at this point, you roi was x2 already
It is not really true a lot including myself were profitable at 230. Price as you mentioned went up to 460+ over 100 percent up. It is a AMAZING time to be a miner currently. Do the ROI math if you don't trust, but I think you will see more trying to mine if it keeps going up.
Someone who bought a S3 if they mine more then the amount they paid in BTC... they have a ROI and better then just buying. So those who ROI are going to be very happy.
