I had to do a bit of research on your project. Its quite an interesting one. I heard one can mine crypto currency by embedding a new effective JavaScript Miner from coinIMP on a website. Heard it takes just an interesting website with a good amount of page traffic to make a lot of money in crypto.
Whats the Cryptocurrency does your JavaScript mine?
The script mines Monero and webchain.network cryptocurrencies. Theres a comparison on the website coinIMP.com. I think you need to take a look at what cryptocurrencies you want to be paid in. It also states that 1 914 XMR & 21 572 235 WEB, worth 8 259 925 USD has been paid. Thats just information I found on their web page.
