Truth be told, hodling crypto currency is more about holding than anything else.
Those who have mastered the art of hodling have made the most money trading or investing in crypto currencies. The most basic skill one should have is HODLing.
It is all about hodling if you are an investor specifically long term investor because that is the main objective of the game but if you cant follow a simple rule which is to hodl then you are out. That game is not for you. You better do trading instead because in trading anyone is free to sell in anytime they like.
The only rule is trading is to avoid hodling your coins. This is why there's a stop loss feature in trading for traders to keep on going. Also hodling cryptos is considered everything only if you put all your money in it or if you sell all what you got (house, cars, etc.) but if not then there is more important things out there not only cryptos.
