You own 5 million HIVE and you are a witness. You own an exchange, which a big part of the HIVE community uses.
Why don't you just provide value to the chain, pump you own bags (and your witness earnings), and promote your exchange. Why go for the 50k in labor costs? I get the computer and server costs, but not the labor.
When you designed the SPS, you asked for 100k. Image hosting is 50k?? Do you realize how important the SPS was to Steem compared to image hosting?
I appreciate your work for HIVE but I'm never voting this. What you should do is provide value and be an example. Don't bill every line of code you write.
