You are in the Bitcoin section. You should move this thread to the altcoin mining section.
Anyway, about wallet to receive doge and LTC why not use non/self-custodial wallets?
Or their official wallets?
Don't use exchanges to receive mine coins it is too risky and you may never receive it from exchanges so self/noncustodial is the right wallet you should use.
You can down the wallet from their official sites link below.
