The distribution rules:
BTC to bytes: 1 BTC of proven balance gives you 62.5 MB (0.0625 GB)
BTC to blackbytes: 1 BTC of proven balance gives you 2.1111 * 62.5 million blackbytes (money supply of blackbytes is 2.1111 times more than that of bytes)
Bytes to bytes: 1 byte on any Byteball address gives you 0.1 new bytes
Bytes to blackbytes: 1 byte on linked Byteball address gives you 0.21111 blackbytes

I received my bytes, but how can I see if I received Blackbytes ?
If you select the Send tab do you see a scroll down list to select blackbytes? The Home tab should also have 2 small dots under the "100 000 bytes" in big large font, clicking the rightmost dot will show the amount of blackbytes.
Many people made the mistake of linking the bytes-address with transition bot, but then made a payment, and all the bytes were moved to other address, so missed the free blackbytes.
