I don't have much, but still have a monero. I would like to use it somehow to place bets. Can you tell me any links where I can use such currency?

In principle, I think in the modern world you can already use almost any currency and you can find suitable links, as this information is not confidential! As for monero betting, I recommend you to familiarize yourself with the link https://betclone.com/crypto/xmr.shtml There are exactly the links you need.
