The 3rd Round distribution on March, do I need to sent my previous byteball balance to new wallet, like 2nd round distribution?
And do I need to linked my new BTC address? or I can use my previous BTC address? which is I use for 2nd round.
You have answers in your questions. YES & YES
I am confused. I guess both answers should be "NO" if I have not moved my funds after the 2nd distribution?
If my understanding is incorrect, please anyone can explain in a bit more details why?
The BTC-to-Byteball address link stays, the transition bot does not forget those links between each round.
And the "linked" Bytes-address to Transition bot, also stays, this "link" is needed to receive blackbytes. This link also stays, but if you made payment with the wallet chances are your bytes are in a different address in the wallet than the one transition bot knows about. So chat with transition bot and move all your bytes to the address known/you-told-about to transition-bot, then you will receive blackbytes.
BTC-address to bytes-address => receive 62.5MB for each 1BTC (that is the ratio, if you have 0.1btc it also works)
bytes-address-known-by-transition bot => receive blackbytes for each byte you hold, in a ratio unknown to me right know.
