Today is a big day for blackbytes: now they can be sent to anyone, even if they are not in Byteball yet, no pairing required.
This is huge!
One question though (and I would test it myself, but don't want to upgrade yet): does the "black text coin" include bytes for the receiving party to be able to move the blackbytes to his wallet? If not, there's no use sending it to someone who doesn't use Byteball yet without adding a "normal" text coin.
Yes, it includes just enough bytes to pay for the fees.
