if I create tx with unconfirmed input and low fee 5-10 sats/byte, size below 500 b
and the input is unconfirmed because of low fee too  , size over 2kb
would it be possible to accelerate that tx using your free service?
would this tx be considered as CPFP tx? hence tx fee parent+child / tx size parent+child?
or your service would auto reject tx with unconfirmed inputs...
