I'm about to start a website similar to Reddit and Pinterest, but my idea is to reward users and to pay them with ETH and latter with ETH based tokens. Idea isn't my own, such website already exist: Mamby.io
but they pay members in BTC.
So, users post content of any type - images, memes, gifs, videos, texts... whatever. More impression they have, more they earn.
I'll be able to create a website but need more knowledge on how to process ETH payments. Imagine there is thousands of users and you have to send them some ETH when they reach a threshold.
What about security? I assume any crypto related site is under attack of many scum. What are risks? What should I pay attention to when it comes to security?
