I just found a pattern regarding BTC/Nexus trading:
BTC up = Nexus up
BTC down = Nexus up
You are right. Nexus had always been my favourite safe heaven, but always it is safe invest too, it has steady grow. There is lots of profit to be made ETH, DASH etc. but there is high risk that you can lose your BTC. That is why when BTC dropped againgst FIAT I will always invest on good projects.
Edit. Just bought about 3500 nexus, so thank to the sellers,who dumped on me.
