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
Having the petience and timing in selling altcois is always a big profit or income but other holders can't help but panic especially if the markets dip but you do it in a way so as not to have big losses you can swap the your altcoins or sales and select the usdt token and rebuy only if the price falls to make a profit in case the price goes up.
You cannot just invest and forget about your assets for a certain period of time. The cryptocurrency market should always be monitored and followed not only by the readings of the charts on the exchanges, but also in the information space to follow the news of the projects in which you have made your investments. This is necessary in order to avoid losses, in order to get rid of a bad investment in time, or, on the contrary, to increase the volume of more withdrawn ones.
