I guess you need to have a lot of free time and some organizational skills... There's no one special place where you can see everything, coinmarketcap and coingecko can be good for some basic searches, but you need to be active on Binance and some other exchanges that have many new listings and promotions with new coins and tokens! Keeping track of all of them really depends on how you will organize yourself, some spreadsheets, lists... I believe the more new projects you include will be harder and more complicated to follow them all, and expensive to invest in all of them!
I think it's better to be active every day as much as you can and when you stumble upon some good project get more interested... after some time you will have a nice list of projects you are interested in, you will be able to follow them and invest in them! Too much of anything is simply not good!
would really be needing that extra effort on making out searches individually and its true that there would be no special or specific place on monitoring this since it could come on various places.
So if you are really serious on not to miss out every single one of it then you would really be needing that effort to do so.
