Today I saw the price of DOGE very high on the Binance exchange, I immediately sold all the DOGE that I have. After I found out why the DOGE price hike was due to tweets from WSB Chairman and Elon Musk. I wonder. Why do famous people's tweets have such an effect on the price of an asset?
Selling an investment is totally depends on your own risk appetite and your conviction of the asset. Now if you are already at gains, it totally depends on you. You could play for 10–50% gains or hold for more long term depending on your conviction and most important your deep study of the market.
