If we see bull market this year which token will be the best profit to hold. Although risk is higher of newer altcoins but older altcoins are now more dependent. Thinking that buying before the bull market will be more profitable!
To be honest, i would say that what you are asking is like wanting a correct spot on prediction on what the price of bitcoin would be at a given time period, you are I know such things is close to impossible to know, if at all it's even possible.
But then, one thing I know for sure is that, some new altcoins will do or perform really well in the coming bull run, while there are others that won't. And same thing goes for old altcoins as well, some of them in do really well in the coming bull run, while there are others that won't, so, it is not our job or duty respectively speaking, to do a proper research, and try the find those altcoins (be it new or old) that we think will perform very well in the coming bull run and invest in them.
Like for example, I discovered chainge finance, this altcoin have not experienced any bull season before, so I placed it under the new altcoin category, I decided to start accumulating the CHNG token after I researched and found how well the developers have done with the project, I see CHNG as the decentralized version of BNB, and if everything should go well, this project will create the next wave of crypto millionaires and Billionaires.
