IS IT POSSIBLE TO MINE BITCOIN IN LOPTOP PLZ TELL ME THE PROCESS?PLEASE TELL ME THE PROCESS.
In short: no. But I believe you can still mine some shitcoins on your laptop (CPU or GPU) and sell/convert them to Bitcoin. I can't comment if it's profitable or not, because I don't have any info on where you are located, what is the electricity price in your country etc.
Any old CPU/GPU have far lower energy efficiency. It's safe to assume it's not profitable, unless electricity price on your location is extremely low.
