after bitcoin unmineable the miner will stop his mining,
Why? Won't he want the transaction fees?
then the network of bitcoin will be down,
Why? Can't I just run my own miner if I want my transaction to confirm?
each transaction will require a very long time to reach 1confirmation,
Why? Shouldn't the difficulty adjust automatically so that blocks still occur on average every 10 minutes?
or need highest fee.
Why? Won't there still be at least 1 MB of space available in the blocks? If nobody is using it, then should my transaction confirm in the next block (since it is the only transaction)?
so the bitcoin user will be use other payment gateway, and bitcoin will be die..
this might happen in the future... ?
That's a whole lot of nonsense and FUD you put in that post.
