I've been following Nano daily since Dec 2017 and I plan to run this node for the foreseeable future. The node has been running 24/7 since Feb 2018 and is currently hosted on a VPS with 4vcpu Intel Xeon, 8GB ram, SSD and 200/200 Mbit/s. I'm managing nanolinks.info, moderator & community manager of r/nanocurrency & Nano Discord and looking forward to continuing supporting Nano in the best possible way.
