Maybe it can be interesting for TRC Community.
I've found this post of crazy_rabbit that states that TRC was created on October 28th, 2012.

I'm seeing the poll you've done so I'd like to add my 2 cents. I feel like GPU miners are the fuel of crypto-popularity because there are many, they've made investments so they spread the word about the coin they are mining. Mergemining doesn't lead the coin to popularity because only a small group of very big investors are mining BTC and they don't have time and interest to discuss or promote small coins. PoS is an ecological choice of course, but it makes big holders even bigger so it's not a good choice and also I feel that PoS doesn't make people promoting the coin they are stacking, because they haven't invested into equipment. Another interesting option could be PoC, which is ecological, but requires equipment. The downside is that the community that has PoC equipment is much smaller than GPU miners. So I'd consider to opt for some GPU, possibly ASICs resistant, mining algorithm, X16R for instance.
