Right now Bitcoin's price is rallying and block are full. According to blockchain.info backlog of unconfirmed transactions is 11.6 MB right now and as far as I know there is now spam or stress test going on. How worse does it need to get?
it seems not as you think,blocks are not full,many people comment like that,and now i just knowing that unconfirmed transactions is 11.6 MB,is not happen many times.
