Thank you for so valuable project!
Also, you are the first who got my witness vote ;)
I am just curious, what do you think about advertising supporters? In theory, you can get a payment of your hosting fees from some advertisers (e.g. from database hostings, startups to monitor/analyze data, or maybe crypto-related). Something like http://httpbin.org or the most open source projects.
And I think you need also add your BTC/ETH wallets (or maybe even PayPal).
