Focusing on the top 300 coins list will certainly be very confusing because it will take a long time to find potential coins. Maybe you can focus on the top 50-100 list of potential coins so that you will have enough time to analyze them one by one and find the right coin for your investment. Or maybe you can look for cheap coins on the top 100 coins list. But don't forget to invest in bitcoin if you want to get big profits in the future and invest in altcoins only for the short term.
He didn't say that we need to invest all of them but then we need to analyse them before we invest. Maybe there is some tools online which we can use to filter out the key functions that we mainly look for. A few of those factors are already mentioned by the OP. That should eliminate most of those coins in the top 300.
Coins higher than on top 300 might not be a gem anymore because they are done doing a great increase with their value and that is the reason why the climb up the ranks. There's only less to expect on them. Hidden gems can also come on those newly released coins and they are better since we can get them cheap and the private sale but btc must be our base since it is more guaranteed than the rest.
Indeed he didn't say that and I just said focusing on the top 300 would be very confusing
Although we can use online tools to find them, it will still not be easy because we have to analyze the coins one by one. But even so, it's still worth doing, as our goal is to find hidden gems.
And I agree that hidden gems can come in newly released coins or tokens because it could be that the new project has something different and has to be the next best. But still, bitcoin will be the best among others.
this reminds me that 2 years ago I spent hours on coinmarketicap researching altcoins that had the potential to increase their prices a lot, but because I spent a lot of time on this search I got tired, so I started looking on sites that (I don't know if yet there are ) listed new and even old altcoins but only if they had some good news, but there were many pages and it took me a lot of time, so much time that I had to stop and the most stressful thing about it all is that I couldn't even make a profit, I just lost a lot time. with that I keep asking myself if it's worth spending hours analyzing one by one project
I would strongly advice newbies staing far from altcoins. BTC, ETH, BNB and maybe 5 more are worth the research. If you think there are "so many good altcoins" - make a list of 10.
I also tell people not to be putting money in altcoins, maybe some might even be worth it, but in the long run altcoins just disappeared or will drop in price a lot, that's why I say just invest in bitcoin, but from what I see many people are still chasing 100X profits, that 100X profit greed that makes people go buy altcoins
