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 to be honest and of course the real situation of the token you're holding, so always be aware if you have such plan.
