I hope you're kidding...

For mining btc, that's the worst decision you can take (well maybe second to buying CPU)

From my limited knowledge, it would be a lot better for you to buy the actual bitcoins themselves and hold on to them to maximize your profit(if you believe the price will keep rising)

It wont just "keep rising". There are its own risks. Most of them result in human error (EX. Price drops $100, and you panic sell all your BTC).

Thats not useful to all coins. Some alt coins are faster for cpu mining... (I think, not 100% sure)...

Obviously thats the best response but people that are not familiar with the concept of difficulty in mining think of miners as magic machines that convert electricity to money. I don't know why they don't ask themselves if that's the case then why companies are selling them and how they choose the price...
