for now I leave assets that are no longer developing and start from the bottom again with new coins that have good potential to grow in the coming year.
Good strategy indeed, but needs to be well driven as long as you really believe that those assets of yours are no longer gaining interest it's better to sell it out and try exploring with new ones that have a good momentum, there's always positive outcome when you really doing your research, keep being updated and select those coins who can bring benefits.
Dealing with your knowledge, so when you go and buy another assets you will have a big edge to gain and not being trapped.
