Now there's a tough question.What in your opinion do you think poses the biggest threat to Bitcoin, in both the short and long term? You seem very confident in the whole Bitcoin movement but you must have doubts.
I'm at an interesting place right now where I think I know exactly how it could be made to fail, but I don't want to say it publicly because the idea could spread and be used against bitcoin.
All I'll say about the threat is that it involves a specific tactic tied to a strong 51% attack technique employed at the same time... By a really major player like the US or China, and soon. I don't know if there is anyone competent enough in those states paying attention to bitcoin, however.
What's likely to happen is some stupid lawmakers thinking they can ban it once it becomes a threat to the USD; and they'll fail miserably. It'll be waaaaay to late then.
After we pass a certain hashing power window, I've got no fears at all.
I'm confident enough in bitcoin to both mine and invest in it until then, but I haven't put the bulk of my savings into it yet simply because there is that small chance that the bitcoin system itself is attacked. (Competently)
Meanwhile, I've got a lot of US fiat and Thai fiat sitting around depreciating that I don't feel comfortable about, so really all I can do for now is diversify and keep helping bitcoin any way I can until we're past the point I'm afraid of.
