I have been reading up on this bitcoin malarky, and I'm certainly left with the impression that even now it's a very good investment. The two biggest concerns are - loss of confidence, and a superior currency replacing it. But bitcoin has emerged from the silkroad seizure stronger, people are MORE confident that it is secure. And while another currency might emerge, there's no reason it can't work alongside bitcoin. Bitcoin only collapses if people stop accepting it as payment, and I don't see why that will happen any time soon, so its value will continue to increase. How much by? Is if worth buying a single bitcoin? I doubt it's a very good short term investment, I'm not interested in making $1k a year through currency speculation. But it certainly might be worth offering a legit service that people can pay for by means of bitcoin.
