Plus, with BitFury online, the cost of a 51% attack just raised to $200 million.
The only reason it is (currently, for a short time) hypothetically possible to 51%-attack the network with a budget in the low hundreds of million of dollars is because most of the miners are not using such efficient 16 nm chips. As the market migrate to these last generation chips, expect the cost to increase to $1+ billion in the next year.
> So if Bitcoin goes down to $30, that's an amazing investment, right? After all, that's a 500% ROI!
Absolutely. Buying at $6 in january 2013, and selling even at $30 would be a 500% ROI and a great investment over 2 years. What is your point?
I think journalists are finally understanding that a big decline in Bitcoin's price is far from a sign of its "death" (since it always survives these drops), and is not even a shocking news anymore. That's why they don't write about it that much.
The number of full nodes decreased in large part because in the early history of Bitcoin in late 2010 or early 2011 your only option to have a secure wallet or to mine reliably was to run a full node locally. But nowadays there are many alternative lightweight clients using the SPV protocol, and a lot of reliable mining pools (it was in mid-2011 that pools started mining more coins than solo miners running full nodes). So of course many users stopped running full nodes.
