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.
No, patience isn't everything. First, you need to be in the right market. If for sure you know you're in a market that can't fail in the next x amount of time then you will find that having patience during times of market turbulence will be much easier. So, don't stick with a market you don't know much about, hold on those you know will do well...
