You can get a USB stick miner that will mine much faster, use less power, and cost less.
The gridseeds use a ridiculously high amount of power since they are so old and out of date.
Even when they first came out years ago, they used too much power compared to anything else SHA256 mining.
If you just bought it, then return it ASAP, the seller took advantage of you selling you old crap.
