Nope, you're on the wrong way. forget about mining bitcoin that's will not giving your amount is back to your pouch. try the others.
It's like kill you, you should for buying your middle GPU level with your such amount and trying mining the other than btc, right? I just not wanna for seeing you will lose your money dude.
150 bucks isn't ideal, still, and you're going to have a slightly difficult time finding a good GPU miner. If you can add just ten or twenty dollars you have a solid RX 470 to mine with, nice card and great performance with games, which makes it good for reselling. Other GPUS have subpar efficiency that makes them not ideal for mining these days.
