I genuinely got interested in bitcoins 12 months ago or so. But at that time it just looked like something exciting and mining looked not that profitable. The break even looked very far to reach. I always kept an eye on bitcoins. A few months ago when it looked really serious I still waited.

And now it looks profitable to mine and invest. Many say I'm too late to mine, many say its still not late.

You have to define our purpose if you want to discuss whether it's too late or not.

1) If you want to mine as way obtaining bitcoins to hold then it's literally never too late. Bitcoin could crash or go to $1,000,000,000

2) If you wanted to mine them to sell for an immediate profit then it is simply too late.
