I've mined bitcoins, and have made a reasonable profit (~20ish BTC or so?). I mined in the GPU days, and while I currently run a small ASIC miner (BFL Jalapeno), it will likely barely be profitable.

The considerable risks and costs of getting into modern ASIC mining make it pretty unattractive at the moment. Until that changes, I'd advise anyone with a profit motive against investing a lot in BTC mining.

If you're confident that Bitcoin will go much higher, and are willing to wait a long while for it to happen, maybe it still could be worth considering. If you just like the idea of Bitcoin, getting a little ASIC miner for fun is entirely respectable. On the grand scale of things, bitcoin is still just a curiousity, and it doesn't hurt to dabble.

With the rise of ASICs, the difficulty level is skyrocketing. I just picked up a Sapphire to play around with, but I'm not sure it'll ever break even.

I wonder if Litecoin mining is more profitable with GPUs?
