hello thank you for interest yeah you will be rewarded equal BCI if you hold Bitcoin on January 22nd by 11:59PM but this estimated time block 505083 is real time BCI will fork and you need to hold fund on supported exchange or to claim your BCI coins after the fork, insert your BTC private key into your BCI wallet. wallet is currently not available, coinbase not supported BCI so if you wanna get it I would recommend transfer fund to supported exchanges, I wont recommend coinbase to store fund because holding fund on exchange sites have some risk like hacking etc. better use blockchain wallet, and here is main site you can check out more information https://www.bitcoininterest.io/
