I am the beginner with Bitcoin and I know that there are great many ways to own Bitcoin such as buying, woking for jobs which pay by Bitcoin, trading orm mining but I am wondering should I buy it or mine it?
Buy it. Mining requires knowledge and involves risks and efforts. It's more fun mining, but you gotta know what you do, if you are wondering or not sure - definitely buy and hodl.
p.s. and don't even think about cloudmining cause you'll get burned.
