Frequently Asked Questions

MinerAlt offers a JavaScript miner for the Monero Blockchain (Why Monero?) that you can embed in your website. Your users run the miner directly in their Browser and mine XMR for you in turn for an ad-free experience, in-game currency or whatever incentives you can come up with.

What about payouts?

Mineralt pays per solved hash. The payout rate is adjusted automatically every few hours based on the global difficulty of the network and the average reward per block. The payout rate is calculated like this:

(solved_hashes)/(global_difficulty) * (block_reward) * 0.7

With the current network difficulty of 29.876G (updated Oct 24, 2017 - 14:59:23) and average block reward of 6.19 XMR (556 USD):

(solved_hashes)/29875768001 * 6.19 XMR * 0.7 =

= 0.000145 XMR (0.013 USD) per 1M hashes.

0.7 means that you as Mineralt’s partner will get 70% of the average XMR we earn. It's important - unlike a traditional mining pool, this rate is fixed, regardless of actual blocks found and the luck involved in finding them. We keep 30% for us to operate this service and to turn a profit.

Why Monero?

Monero is a secure, private, and untraceable cryptocurrency. It is open-source and accessible to all. With Monero, you are your own bank. Only you control and are responsible for your funds. Your accounts and transactions are kept private from prying eyes.

Why JavaScript and Browser?

As you know, you need to calculate hashes to cryptocurrency mining. The Cryptonight algorithm is used to mine Monero's hash. A distinctive feature of this algorithm is that it works well on consumers’ CPUs. Therefore, it can be used with JavaScript in the browsers of your site’s visitors.

Mineralt uses WebAssembly. For the Intel i7 CPU (one of the fastest desktop CPU), you see hashrate of about 90 hashes per second.

The Mineralt team is working on optimizing of our script and we hope to improve performance in the near future.

Minimum payout amount

Mineralt works with as much transparency as possible. If your users solve hashes, you get paid. The minimum payout threshold is 0.05 XMR (~$4). Mineralt makes payouts by request to PayPal, XMR, Payza, Webmoney and many other systems. We pay 4-5 times a week.

Does Mineralt have any additional fees? Do I need to pay for anything here?

No. You do not need to pay anything. Also, we have no fees that are charged for payments.

How much can I earn with Mineralt?

It depends on traffic on your site. If you have a blog that gets 10 visits per a day, the payout will be small. But if you an owner of video site with big audience, you can earn hundreds USD per day.

In other words, earnings directly depend on the processor's power of visitors on your site and on the length of the visitors’ sessions. Mineralt is a solid increase in your revenue stream from traditional types of earnings (popups, banners and etc), but you shouldn't compare Mineralt with professional mining on expensive video cards or ASIC.

Do you have an affiliate program? Where can I get a link to invite new partners?

Yes, we have an affiliate program. We pay 5% of earned by the partner invited by your link. You can invite new partners by the link in our affiliate program. All partners, who will register by your link, will be marked as your referrals and you will receive a percentage of their income.
