Too much expectations. Given my direct experience 1000 COSS will give you around 20 cents /week as of now. Frankly you will need to pay some extra fee to distribute those 20 cents (in form of various alts) to you wallets
Convert other coins from non-ERC20 to ether (it's free), but do not distribute (there's fee). Keep them for awhile until you accumulate enough of them to justify paying the distribution fee.
The reason for converting other type of coins to ETH is so that you wouldn't need all hundred different wallets for each different coins.
You only need just ETH wallet to receive all the weekly fee splits.
