I didn't receive blackbytes yet. This was my first airdrop received from this coin. GB I received on the same day of airdrop but blackbytes not yet. Is it common these coins will come in later or we need to do any extra settings to do to receive these blackbytes?

Distribution of bytes is finished, 110,411.089425997 GB distributed.  New available supply is 365,903.008377294 GB.  It is already updated on coinmarketcap.

Distribution of blackbytes will start in a few hours and will take much longer, likely more than 1 day.  I'll post when it is done.
