I have around 100-150 dollars and was wondering what would be the best thing to get.
Buy GH/s on cex.io
Site is well set up and pays well. Hosting your own miners is silly
Never follow investment advice posted in the Newbies forum. If a scammer is going to post on these forums, it will most likely be in the Newbies forum.
Now, I have no reason to doubt Kyle's integrity, but I have to question his judgement. He is recommending that you send your money to an anonymous person on the internet. The world of bitcoin is filled with scammers. Given that nothing is known about cex.io, how can he possibly assure you that it is not a scam? Do not send any money to this site (or any other site) until you know enough about it to be reasonably certain that it is legit.
Now, before you spend any money on mining equipment or mining contracts, it it crucial that you understand the financial aspects of mining (unless you don't care if you lose money). Losing money on mining is a classic newbie mistake. Most newbies lose money on mining.
I estimate that 1 GH/s is worth about 0.2 BTC at most because of the skyrocketing difficulty. If you pay (or recently paid) 0.24 BTC per GH/s, you are going to lose money.
