I think that privacy coins will be more and more in demand so I like to invest in those now.
One of my picks is GoByte (GBX). It is a privacy coin that has masternodes and it had a nice rise before recent crypto market crash. They have several great updates coming soon and I think that GBX will be a nice coin to hold in the future.
Second one is DeepOnion (ONION). This is a coin that gave me biggest profit out of any investment in crypto that I had. Development is very fast lately and new updates are coming all the time. I think that it will have a strong growth very soon and I am trying to accumulate as much as I can.
