Many thanks Krypt, Gtswpm60, jwinterm!!
Now I have a better understanding

But I still have some doubts.. The price today is around 66$. It means 1 byte = 66$?
Then.. if you have 1BTC during the snapshot, and you receive the bytes. Later on can you move the 1BTC out of the wallet without losing any byte?
Thanks in advance!!!
No, 1,000,000,000 bytes = $66
after snapshot you will free to move your bytes or BTC without loosing any
