The market is collapsing

That doesn't matter in the long run. The blockchain technology is same as yesterday or even better. I'm still holding my ICO coins and mining on JoenNL's pool. I had issues with power and Internet outages for the past few days. Now I have issues with Cast XMR (the miner would randomly stop hashing)... But I'm not quitting! I will switch to SRBMiner and keep mining.
Also, if you are not on JoenNL's pool, this is the
right moment to join. The configuration is super easy if you have your own ETN wallet address. Join today and don't miss out on the fun!

I am not sure if this helps but my cast xmr had conflict with windows 10 firewall. When I mine, I turn all of those protection off.
