adding Sinovate to coins.json
I'm trying to add Sinovate to coins.json and I did as following:
`  "sin": {
        "name": "Sinovate",
        "symbol": "sin",
        "family": "bitcoin",
        "coinbaseHasher": {
            "hash": "sha256d"
        },
        "headerHasher": {
            "hash": "x25x"
        },
        "blockHasher": {
            "hash": "reverse",
            "args": [ { "hash": "x25x" } ]
        },
        "hasPayee": true,
        "explorerBlockLink": "http://explorer.sinovate.io/block/$hash$",
        "explorerTxLink": "http://explorer.sinovate.io/tx/{0}",
        "explorerAccountLink": "http://explorer.sinovate.io/address/{0}"
    },`

but when it wants to submit a block I'm facing the following error:
'Block 183316 submission failed with: bad-cb-dev-fee'
any Idea how to fix it? I added '"hasPayee": true,' but still the same.

@oliverw you added this coin to CF, can you please post the setting here? thanks
