I planning to learn bitcoin mining, but is it too late / not worth to mine bitcoin now ?
Well, if you take the time to study Bitcoin and how it works, then i think you will get the answer that you are looking for. Go ahead, try it. I promise you, with a little effort comes little rewards, but with greater efforts, then the greater the rewards will be. But hey, that's completely your choice. Oh well, just go and check your resources. Add them all up and subtract it with yiur monthly income in mining. Doing so will make you see if you have gained profits or not.
