Old usb mining ASIC stick with 300MHs hash rate is useless.
Proper hardware today is in a terahash scale.
If you just want to try mining as a hobby with a USB ASIC stick, then I would suggest you Gekkoscience 2Pac stick, see here https://bitcointalksearch.org/topic/general-sales-closed-gekkoscience-2pac-2x-bm1384-usb-stick-miner-1718358
why is there no profit for PC based mining ?

i actually want to invest in to a new GPU maybe decide later, Should I. (if i do what would you suggest)
Thanks
In Bitcoin mining, there is no profit for PC based mining.
It is done with ASIC hardware.
Alternative cryptocurrencies like Ethereum, Zcash .... are a different story.
Those coins can be mined nicely with high-end graphics cards PC setup.
sorry for my fools
thanks by the way
i gotta learn more about all of it , which forum would suggest for learning
This is a good forum,my choice for finding out what cards do what hashrate & how to set em up
