I am completely new to this mining lesson and have not even started yet. Is that possible to mine bitcoin with a high-end laptop or a pc? have anyone tried it and is that profitable?
If you are looking for ways to get Bitcoin and you are considering mining as an option, know firstly, that it is not possible to mine with your laptop, no matter how high-end it is, and that mining is very cost-intensive, and demands you to be sure that it is what you want to do before starting. It requires equipment, requires adequate electricity, requires proper space and some other factors like the legal nature of mining in your country if you want to make your mining a success.
And like I have said before,
If there is any application or software that the developers tag as being able to mine bitcoins, it is fake and should be avoided.
