Over the past few weeks, I've been experimenting with Monero mining. During my research, I stumbled across a site called "xmrbazaar". It looked pretty interesting, so I thought I'd give it a try. It's pretty much a marketplace where people can buy and sell things for Monero. There are jobs, books, electronics, even cars. It's free to sign up and looks pretty secure. However, it is p2p and there are definitely a lot of scammers. There admins and mediators are good though, and so far everything has worked out fine for me. I've just been sticking with vendors that have a lot of good reviews and support mediators. I recommend taking a look if you have Monero, but of course be very careful and never spend a lot.
