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
You right. We need more than patience to profit when investing in crypto
but if you have found a project that has the potential for success, patience is the only thing you need most to get maximum profit.
Long-term holding is good only for the potential projects but not for the shitcoins. I'm not sure what coins that OP had to hold but it possible, it was those coins that I've mentioned above.
I have the patience in holding but not necessarily have to do it, especially when I saw that my investment is in trouble. We need to take action immediately, selling might be a good idea rather than to keep holding even we know that it is already hopeless to see it coming back high.
