From the several altcoins you mentioned, it seems like Matic and BNB are the best choices for investment, while Cardano is currently not doing well. As much as possible, don't divide too many assets among the altcoins you have, and as much as possible, focus on just a few altcoins to get maximum results.
I don't know enough about technology to compare the advantages of Cardano and Tezos, and we're talking about investments, so I'll talk about the prices of ADA and XTZ, specifically about their growth potential.
1. ADA: top 9 on Coinmarketcap, created a new ATH in 2021 and is being mentioned thanks to the continuous development of Cardano. Currently ADA price has broken above Dragon EMA34W.
2. XTZ: top 80 on Coinmarketcap, was unable to create a new ATH in 2021, rarely mentioned by the community. Currently, XTZ price has also broken above Dragon EMA34.
From a personal standpoint, I would choose ADA over XTZ.
