Do you sell because of the rise/deep in the market, or do you sell because you actually needed the money and not because of the deep/rise of the price, or you're the type that just jumps in pick some profits and jump out?
I am a long term holder of altcoins. I sell my tokens (both alts and bitcoin) when I am broke, and when I need some money. I don't sell because there is a deep in the market, I sell because I need to. So, what about you?
Maybe they sell it because that is the right time, holding is selling is already a business to many people they just waiting for the right time to sell that coins when it already hits its highest value in the certain span of time. It is a profitable business that is why they sell it because if they did not there is no essence of holding a coin that is why they sell it.
