How effective are USB Scrypt miners?

[rebel24]

I want to mine scrypt but I have a laptop... so I need a solution and the easiest seems to be USB Scrypt miners,
how good of hashrates do I get though? Is it comparable at least to a GPU or a few GPU's(if a have a few usb miners running?) Whats your feedback?

Anyone know a good deal of where to get them as well?

it is hard to use online calculator?

just type google > mining calculator

thats all!

good luck

I got 4 block erupter, i got it for free at bitcoins4currency.com and in the begining it was very profitable but now is not that much.

guys it is real easy to calculate profit..

but anyway with few usb erupters and according to difficult you will mine like almost nothing.

You can try your erupters to mine some new alt coin but ... it might be a waste of time as well

The only USB Scrypt miners I have seen are the "Scriptor Solo" FPGA from http://ltcgear.com/, those only hash at like 25-45kH/s each. I thought about buying some back when they were in-stock last year. It might not seem like a lot of speed but the low power cost is nice.

Alternatively you might just want to check into Cloud Mining which can be a little expensive, but then you don't have to buy any hardware.
