Btc is always the best to invest in crypto .It is a good list you made here is all the top project included .I think it is always better to invest on the top coin on market it is making you sure that if you hold it for long term you can get a good return .That's why i always suggest to invest on the top coin .On more thing i wanna say from the list you given here from that i wanna choose the DOT,Matic and LTC those are more strong project on altcoin .So guys you can also choose this but DYOR before invest always .
for me for the long term I just choose bitcoin and that is enough, unless we want a bigger profit, then we can choose another altcoin that is at the top of the coinmarketcap, where these altcoints have a greater chance than other altcoins , but if we understand the market movement, we can wait for the best price to buy
