i am quite new to ethereum and i have been reading about deploying contracts. Do i have to necessarily buy ether using bitcoins or i can mine them up straight and how long does it take to make some initial value of a contract once you start moving
Qn on the transactions in a block: it appears that the transactions collected into a block by two winning nodes could be completely different both in order and the actual transactions. Is that so or are all transactions ordered the same on every block which come up together with a PoW?
I understand that it will be ordered by timestamp, but even then two transactions could be initiated at the same time, right?
