However, my point is, is Bitcoin development so difficult? Is it a thing from the past? Nobody writes bitcoin-related software anymore? Why on earth isn't there any good bitcoin-related product advertised in the forum?
Is it because bitcoin projects can't be easily monetized?
Is it because even if they were monetized, they couldn't have the profit margins that casinos have, so they could be efficiently advertised?
Or is it because only mixers could bring money to the campaingers? I highly doubt that banning mixers was such a powerful measure, that lead to the "all-in" from signature campaings...
Well, this place used to be full of Bitcoin projects. The problem has always been trolls. Look at my Nasty project for example. I raised $400 to run a home miner for the community, turned it into an organization worth over a million dollars, distributed nearly a thousand BTC to participants, sold thousands of physical coins made from precious metals, and the entire time all I've heard from members here is how I'm running some sort of ponzi scheme or scam. Can you imagine spending more than a dozen years of your life running hot loud equipment in your house, paying all the electricity bills/air conditioning repairs, working with designers and manufacturers on products, dropping everything to engrave coins when they're ordered, responding to questions, and then have people leave you negative trust or bash your efforts as anything but altruistic on behalf of the Bitcoin community? That's the environment people running Bitcoin projects have to deal with here. The worst part, it's the people in default trust that enable and even support this behavior.
You will get lots of responses to your questions, but this is the only one that comes from someone with any experience actually running a real Bitcoin project here.
