Start with mining help

[shadowhlohavec]

Hello everybody I ´m new in crypto mining and I have few questions

I wanted to start mining some Worldcoins with my GPU (NVIDIA Geforce 315, 2767MB, laptop) I know that I don't have good gpu for this but I only wanted to try it so I downloaded wdc blockchain and the multiminer but It shows that I have OpenCl and 0 KH/s so i'm asking where's the problem ? 

I also planned to buy Antminer u3 USB miner ASIC Bitcoin mining 63GH BTC Gridseed USB (power-100 wats) for 60$ and I tried to calculate the profitability through http://www.coinwarz.com/cryptocurrency but on the scrypt there is only KH/s,  I figured out that 63 Gh/s is 63 000 000 Kh/s and i typed it in to the coinwarz and it showed about $2,802 profit on mining wdc per day which is bullshi*

I would be glad if you answer me or post some guides about hashrates and altcoin mining where I can find answers

Sorry for english
Thanks

Antminer u3 USB miner and Gridseed USB are SHA-256 miners NOT Scrypt!

Gridseed actually DID make Scrypt miners - their GC3355 chip did both SHA256 AND Scrypt, but it's horribly outdated and a total money-loser on SHA256 now and it's at best marginal even at LOW electric cost on Scrypt - you'd never make your money back on any GC3355 based miner unless PERHAPS if you have free electricity.

 U3 is a SHA256 (Bitcoin) miner, you need to use a Bitcoin calculator like https://bitcoinwisdom.com/bitcoin/calculator

 *BUT*

 The U3 is also old and outdated, unless you have FREE electricity you'll never make enough mined Bitcoin to pay for it.



 Mining on a laptop is a good way to KILL the laptop, even if you have one with enough of a GPU to actuall mine with.
 I definitely recommend AGAINST that idea.
