Is it really a big mistake to sell portion of your bitcoin and then rebuy back when the price has dip?
Be very careful. People like to talk about this like it is a winning situation but how many times have you heard of someone getting rich this way? One mistake can cause massive damage if you are trying to earn a lot. I know some people who are still waiting for Bitcoin to crash to $10000 to rebuy. They were so sure that it would go back down there but it never even came close to it.
