How do you find these projects?, What makes you invest so much money in such projects, $ 20k is no small sum. An expensive lesson, as a newbie, I don't advise you to listen to any advice from anyone on YouTube or social media. The best thing for you right now is not to invest in which coins but to invest your knowledge first.
When you have the knowledge, you will know what to do next in this market. Remember: Do not listen to anyone's investment unless you fully understand it.
Most of those who are promoting these coins are paid scammers trying to convince you to invest money into those fake projects and once they get good amount of money they just scammed and YouTube guy would not say anything about it so it's better not to listen to them and make your own decision based on some research of your own.
