Hi,
I just made a game in javascript, you can try it out here:

By playing this game you are mining cryptocurrency Monero and you are making me rich, haha!
If you want to incorporate a cryptocurrency miner, you can do it easily with this https://coinhive.com/. It is super easy!
Here is a wonderful tutorial by @ivanli, which i followed to use the miner.
Also the best thing about this is, i bought the server hosting by Ethereum, cryptocurrencies get adopted faster and faster! I love these times, the future of cryptos is very bright!
