Not every individual that learns this way, some will not learn but continue to be investing in the short term. The only time we should sell our Bitcoin is when we are in profits and we want to use the profits to do something more important than investing in Bitcoin. If we aren't in profits, we shouldn't sell in loss because we'll regret doing that. There should be other sources of income that we can use to take care of others things that aren't important and only the things that need more money that can be gotten from the profits that we have had from holding Bitcoin. Our emotions shouldn't be listened to when investing, if we follow our emotion we'll be selling when we feel fear. Investing in Bitcoin, both when we're buying or selling should be done based on our research and not emotions.
