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?
I only sell when reach the taget of me.

don't sell when the market goes down. That is not a good way to invest
Because we need money to buy something that we need or buy what are the nescessary things that we want in our life. We want to spent our family out of town that is the main reason why we sell our coin.
