Bitcoin is not easy to mine, if you said altcoins, that would have been better cause most of them are very easy to mine and mining them are even more profitable than when you're buying. Since you said Bitcoin, I would say it is best for anyone to just buy and speculate, instead of mining. Unless you know that you can afford the cost for mining then you can go ahead for it and buy the equipment's that you will be needing for it, the hot hardware of course, then start mining. That's the last thing I ever plan to do. My friend used to mine Bitcoin but he couldn't bear the cost of it, so he had to quit from mining and sell the hardwares and focused on buying Bitcoin. The case might not be the same for everyone.
