What kind of stake do you prefer? To stake altcoins on exchange, or in the wallet? For example you can stake BNB in Trust wallet and stake them on Binance. The differences are in % and obligatory to pass KYC or not (and such trifle as "not your key, not your crypto"). If passing KYC is not a problem, why not get any top altcoins, that Binance offer high % for staking? For mentioned Matic Binance now offer 6% APY.
