Everything depends on you! What is the moment of withdrawal you have for yourself and act! But, of course, now is not the time to close our positions on bitcoin, but many of Atkoins will not return to their original prices. This is my personal opinion and can not be 100% true! As you know, those who were able to hold their bitcoin since it was introduced are multi dollar millionaires now. As long as you don't need money or you are not planning to invest on anything, just keep your bitcoin because bitcoin is not yet widely adapted by people. Just imagine if people start adapting cryptocurrency and using it in their daily lives, early investors will have a huge advantage.
