In OP there is an instruction how to link your BTC wallet with byteball but what If I would like to get new bytes for bytes I got from first distribution? Do I need to link byteball wallet somehow? I only actively participated at the begining and keeping bytes in my wallet since then. Did I miss 2nd 3rd and 4th distribution or maybe byteball wallets are getting another shares automatically?
Technically, one links a BTC address to a Byteball address so when you link a BTC address, you actually link a Byteball address too. Bytes for bytes do not depend on linking, however only linked Byteball addresses get credited with blackbytes. Given the fact that you participated in the first round and that you didn't move your bytes meanwhile, then you must have gotten bytes and blackbytes from the following rounds.
