I'm not sure if you're being sarcastic or not but thanks for the feedback. The site has no ads or trackers or anything shady (there is no backend, only a client side SPA), the code is open sourced https://github.com/atfides/atfides :)
Thanks for your thoughts and feedback. I personally have a block list for prices or anything quick money making-ish. This project was something I could finish fast and explore what's next, maybe in the crypto space :)
Also btc, ltc or eth public addresses are the only thing meant to be entered on that one text field. If people could grab your cash just by knowing your public address then no one would waste their time in crypto-land.
