There's really a lot to consider whether a coin is worth investing but mostly some people buy it if its listed to big exchange like Binance which leads to pumping, some people think it's nice to buy those kinds of coins since they are new and fresh and it is listed on big exchange.
But me, I still choose the old coins with has a big market cap already rather than investing to lowcap coins which some people managed to control or manipulate.
If it is listed on a large stock exchange, of course, the increase in market capitalization will increase. The new coins are actually fun to trade. the hype was created and the trade was still bustling.
but many choose top market assets for investment and also choose new coins for day trading. those who know the potential of the project will love the hype.
