If I want to start trading altcoins but particularly those meme coins and weird coins that come out, what wallet would you need for that?
There is a difference between trading and holding.
You don't need a wallet for trading, buy weird coins/ or tokens from a exchnage where they're listed, and sell them when you are in profit.
Whereas in holding you buy a coin and hold it for a period of time for that reason you need a wallet. And since you already have Ledger Nano S you can hold in this wallet.
I heard about metamask. That is an online wallet. So if you connect the metamask to the nano ledger s plus, than that would work?
Yes, here is rhe video tutorial:

if it is on ethereum chain then it is listed on uniswap or sushiswap and if the token is created upon binance smartchain then it would be listed on pancakeswap before any centralised exchange.
