I mine at a loss because I can. RVN is a hobby. I have a real job so I can afford to wait. I mined BTC for over a year at a loss in 2013. I waited. I am happy I did. I do not belong to any group. I do not take orders from any devs/miners. I mine on home PCs with decent graphics cards. If RVN collapses I can still play video games in 4K with my kids. I recognized that RVN has potential huge upside with very little downside. I bought a bag when it was over 5 cents on Cryptobridge because my hash rate is really low. Im underwater by 74%, but that is not the point.
Sure, Ive lost real money in RVN already, and I may lose it all, but I dont care. Im willing to risk loosing everything now (not much) for potential gain of loads more later, but to have a chance requires supporting the network now.
If everyone trades, or mines and dumps, we all lose.
I guess Im just a real HODLER.
