Where to buy and store these coins?

I am trying to find a solution to buy altcoins like Tron, digibyte,holo,revain,algorand,neo,cosmos,fantom,matic,vechain etc…

However exchanges like Coinbase, Binance is giving hard time on KYC so I am looking for one place where I can buy all these crypto ..if I can not buy under one roof…at least I should be able to convert to desired crypto.

Also, looking to store them …I checked hardware wallet like trezor 1 but none of them can store all.

So what is the solution?
