I assume that means you won’t be around such threads any more, which is good because you haven’t debunked anything.
You have yet to present any such considerations. Again, the only arguments I have heard are:
1) Bitcoin will fail because I know it will fail and everyone agrees with me because my reasoning is not flawed.
2) “How will you convince anyone to use bitcoin?”
3) Bitcoin is a pyramid scheme. Everyone using bitcoins is a speculator.
4) By virtue of being unbacked, Bitcoin is at the mercy of the Establishment because it has nothing but its convertibility into other fiat monies. (As if bitcoins couldn’t be traded for anything else…oh wait, isn’t that kind of what they do?.)
If I’ve missed anything please enlighten me. But to be honest if this is the best anyone can come up with, I really don’t see how people could be so sure of themselves and still call others “irrational.”
