did u read this sentence ? i mined at eligus but i just got 14 satoshis in 24h
That is what you'll get when you mine Bitcoin with GPU.
This is the era of specialized ASIC hardware for Bitcoin mining. GPU mining is now outdated. You can do it for fun, but you will hardly earn any Bitcoins.
If you still want to mine with your GPU, look at alt-coin mining. Many coins support GPU mining and you can convert them to Bitcoins.
There are also some multi-pools where they mine most profitable alt-coins and automatically convert them to BTC and pay you in BTC. Some examples are clevermining and wafflepool. Just google it.
