I like the idea of cryptocurrency, but I have some doubts about the longevity of Bitcoin. As Bitcoin grows, there is a greater need for mining. However, as Bitcoin grows, the returns for mining diminish.
Would it be possible for someone to deliver the 'death blow' to Bitcoin right now, by DDOS-ing the network or flooding it with even more transactions, including invalid ones ?
Perhaps block chain should accept only hashes of a set of transactions without restricting the set size, and store the actual transaction data elsewhere. This can increase the bandwidth, but will it become less secure, I don't know..
Well, if you query the state, you are bound to get quite a few unconfirmed number at any given time. But they EVENTUALLY do confirm, whether its 10, 15 or 30 minutes at most.
Increase your transaction fees, get them confirmed faster.<p><a href="https://bitcoinfees.21.co/" rel="nofollow">https://bitcoinfees.21.co/</a>
