This shows you quite nicely what all the alt-coins did during the previous two run-ups. You can see that they all mostly jump with bitcoin and then slowly descend as their bubble fades...

Yes that is correct, the private key is all you need to get those coins, so keep it safe

Traditional wisdom says that price does not follow difficulty.  If anything, it is the other way round and difficulty follows price as mining becomes more lucrative.

So why has the somewhat bearish market of the last couple of months seen not only the highest difficulties on record, but also the largest difficulty jumps?

Is the difficulty lagging behind the price? and if so, is the whole ASIC mining scene going to come tumbling down as people realize they have been scammed with effectively useless devices for which they will never recover their initial investment?

Ah, I see, here is my address:

If it concerns you, keep your cryptocurrency in cold storage (this might be something you already do) and only use a small amount on cloud-based services.  This is the great thing about the base protocol, it is trustless.

Sucks man 
Personally, I always to the 6 character check:
I check the first and last three characters of the address before sending.

I guess, technically it could still eff-up but it eliminates a lot of the risk.

Hours of fun, and you can actually use some skill...

Yes, Bitcoins are expensive, however, I believe that what is important (in terms of trading and speculating) is their long term potential and % change in value over time, I believe that people are put-off by the idea of not being able to own a whole bitcoin, I would propose denominations on the Satoshi Scale as follows:

10 = 1 Gigoshi
1 = 1 Bitcoin
0.01 = 1 Megoshi
0.00001 = 1 Kiloshi
0.000001 = 1 Hectoshi
0.0000001 = 1 Decoshi
0.00000001= 1 Satoshi
