Just pick a altcoin ether bnb and check their price conditions during bull run. Specially 2017 and 2021 where bull run is happened. Then You'll see how fast they were grow. Actually durning bullRun all altcoins pump because whales buy a lot. Thats why people also buy a lot. Some altcoins pump more than imagination. But there are shitcoins, those Weren't pump much during bull run. Even some shitcoins are on the top position, which are fail to pump during bullRun. For example Tron(trx) but people still using for some facilities. Well you are newbie, so Don't make mistake and get scammed for First time. Only buy potential and good altcoins
For etherium, it has the potential to return as a blue chip altcoin which is in the spotlight today, and also Ether has a very good reputation and is running as big as it is now, 2017-2021 has provided enough significant benefits for its holders, but for BNB itself today it has received criticism from the SEC, I don't know how in the future it will end up being the same case as the SEC against XRP which has a long enough time, even though BNB also has a fairly broad ecosystem but the problem of demands issued by the SEC is really disturbing , so I think BNB is very confusing for the future in this Bullrun cycle.
There are indeed a lot of Shitcoins and that has no effect on the bullrun, but there are some shitcoins that provide benefits to their holders, we can't see that with one eye, we know that ETH was also very cheap at first, but over time it has made it what it is today.
