When it comes to mining then i won't recommend using our own pc because we need powerful hardware for mining and its always not available. But we can mine monero on our pc as it's profitable than mining bitcoin

Well I think that investments masternodes can be a good if we do wisely as it can provide us a good side income. But make sure we research on that before we start investing.

Browser mining is not fake its real in fact some websites use cryptocurrency mining program so when you visit their website they use your computer resources and mine cryptocurrency that time you may notice that your computer performance is slowing down.

Answer for this is yes because by mining Bitcoin on computer we don't get any profit rather we get huge loss because Bitcoin mining requires is powerful hardware I mean that you need good hash power in order to mine Bitcoin. Also it can heat up and damage computer.

For mining we need much hash power in normal smartphones and PC its not available we need personalised hardware for mining. If we Mine on our own PC or laptop it would just be a waste of electricity and time. Well cloud mining is a good idea.
