I've taken out profits and threw them into savings. I have been hitting anywhere from 2-8x ROI which doesnt seem like much, but I am also not investing a few hundred dollars. Overall, I will ride the wave until ultimately many tokens/coins scale back. I have a few people I follow religiously on twitter and watch many you tube videos daily.
I put all of my domain activity on hold in the mean time... Its been a good December for me. I plan on making January just as good.
