Assuming I've made up my mind to hold on to a token for many years but after a year this token hit a new ATH what should I do as a newbie? Sell or not sell?
it depends what situation it has mate, i mean you really need to keep updated so that you know when to sell or if its still a good decision to hold.. It's all up to you and the real situation of the token you're holding, so always be aware if you have such plan.
Well if he can get the best price at the top then it's no problem if he wants to sell since crypto can down a lot after it reaches its ATH. But we never know the ATH and the movement market right so if you invest in something it's better to have your own strategy, own your target sell so you will be grateful for what you did and even if you didn't get the best price when selling your assets just make it your experience and get better next time.
