In reality, I feel like the new/old distinction isn't too much of an issue because we often get FOMO during price increase cycles regardless of the product's age. And as long as bullish sentiment is enough to make us act, either way, there are opportunities/risks.

Like recently I was considering choosing between TONCOIN and SOL, but looking back, both have had strong performance with quite impressive price increases. So no matter from any angle, the investment plan should be clear from the start and accept everything that will happen even if it is a bad situation.
