Hey! Welcome to Bitcointalk. I hope you find a few buyers for your script. Will you be pushing out updates and supporting your script in the future?
One thing about Coinhive: it sucks. The payouts are bad, they have a ridiculous fee structure, and a very, very high minimum withdrawal. You should consider looking into
WebMinePool. They have a higher payout than Coinhive (around twice as much per million hashes), no fees, and a payout straight to FaucetHub. No exchange fees and no commissions. I highly recommend looking into it.
Hey! Thanks for your reaction. Maybe I'll do a big update where you can choose between WebMinePool and CoinHive!
