Let assume you only have $1000 and you can put this money in 1-5 projects but they all have to be either old tokens or new tokens that you'll be buying. Which one will you go for, for those that will think they can choose the two type of projects, that won't be possible. I'm trying to see where the attention of investors go when selecting tokens to invest into for the altcoin season.
Ideally, I would not want to invest in either old or new tokens. For me, it's like trying to choose which shit is better: dog or cat.
But since you pose the question this way, I would prefer (hypothetically) to invest in new tokens, because the effect of novelty will influence investor interest and these projects can make a short-term profit due to the hype on them. Old tokens look like slowly dying projects that are no longer interesting to anyone and will not be able to cause the excitement that was at their start.
