When you decide to sell, be it today or tomorrow or whenever, chances are you will sell at the bottom. This will cause you massive depression, way worse than not selling at the peak to rebuy cheaper.
Buy and hold, or risk selling at the bottom and losing your position. After this dip stabilizes, we are going $2000.
i have been always telling people for years that they have to make up their minds before going in. before wasting their money by investing in bitcoin and be scared all the time.
you either have to be a day trader or a long term hodler.
make up your mind before buying.
if you are a day trader then you have to be able to analyze the market every second, and make decisions every second and be successful.
if you are a long term hodler then close the damn price reporting sites like preev,... and keep hodling for years not for weeks.
