When I was still a newbie to crypto many people told me to keep holding and that's all I did for many years and in the end I ended up with many dead coins, whenever I keep seeing people talking about patience as if it's the only thing a newbie need I always shake my head, the fact is you need more than patience to get good results from projects, having patience sometimes will get you nothing
That's bad advice for HODLING, not all coins are worth HODLING for a long you shoulkd follow the development if it's a new coin and you should sell anytime you see that there are no development on going on that new coin, it is ok if it's a coin that's proven itself in the community, like Bitcoin, Ethereum and Binance coin, but if it's a new coin you should be extra careful on HODLING too long.
