Hello,
I just discovered the possibility of browser mining and Nimiq has received quite a bit of buzz. However, it isn't actually live yet. Are there currently (trustworthy) alternatives?
Are you speaking about bitcoin cloud mining. If I am right. You are moving towards the wrong way and you will loose all your money in the buying hash rate from the network pools.
I suggest you purchase the multiple graphic cards to start the mining altcoins. I hope you can make decent income with the commercial rental electricity charge too.
