Mining statistics dashboard I am searching for a public mining statistics dashboard that lets you see per BTC address/transaction how much was mined, when, and a way of making sure that those Bitcoins indeed come from a miner. It is necessary for tax purposes.
Any block explorer should do, if the address contains coinbase inputs (not to be confused with the company) then there's your proof of mined coins.
