If safe dev decides to increase to 64 bit, then it will be 2.1 quadrillion coins. But, that still won’t solve the micropayment like smacz stated. micro payments works wonder if there is a decimal in place. Even more so, safecoin cannot be divided since it is a data entity. How does one split up datastructure?
I dived into rust documenation. It states that it could borrow data from that insistence, and manipulate it. However, it cannot be borrowed again. It has to return into the rightful owner. It cannot be destroyed unless it returns to rightful owner. It cannot transfer to another owner, until it returns to the rightful owner.
So it is theoretically possible to transform safecoin into divisibility coins. 1sc into 99999999 altcoins. Altcoin could be used for specific things. But all of the coins must return so that 1sc can transfer to new owner.
OT: This mean safecoin itself is not just a coin. It is fuel to create co-operatives organizations. @Seneca explained this very well to me in bitlaw part 1 and part 2 thread.
If safecoin cannot be divided then we need another coin for micro payments. And it means more work for transaction manager.
