In a test of Bitcoin's ability to adapt to its own growing popularity, the Bitcoin community is facing a dilemma: how to change Bitcoin's core software so that the growing volume of transactions doesn't overwhelm the network. Some fear that the network, as it's currently designed, could become overwhelmed as early as next year.
The answer will help determine the form Bitcoin's network takes as it matures. But the loose-knit community of Bitcoin users is not in agreement over how it should proceed, and the nature of Bitcoin, a technology neither owned nor controlled by any one person or entity, could make the impending decision-making process challenging. At the very least it represents a cloud of uncertainty hanging over Bitcoin's long-term future.
The technical problem, which most agree is solvable, is that Bitcoin's network now has a fixed capacity for transactions. Before he or she disappeared, Bitcoin's mysterious creator, Satoshi Nakamoto, limited the size of a "block," or group of transactions, to one megabyte.
Under the one-megabyte-per-block limit, the network can process only about three transactions per second. If Bitcoin becomes a mainstream payment system, or even a platform for all kinds of other online business besides payments (see "Why Bitcoin Could Be Much More Than a Currency"), it's going to have to process a lot more. Visa, by comparison, says its network can process more than 24,000 transactions per second.

Bitcoin is extraordinarily susceptible to theft when not left to rot away in a private wallet.
That's why you keep them offline until you need them, and only use each private key once. I understand that this is cumbersome, and not ready for end-users. If/when we see a secure, easy interface for using bitcoins I suspect that it will come in the form of dedicated hardware.
