Refer to my prior blog about the capital controls and “proof of source of funds” confiscations that are coming to kick people off of their BTC.

Any other attacks other than the $5 wrench attack that I need to worry about? I know better than to hold on exchanges and use a cold wallet. I'm not in the habit of describing my opsec, but I'm only really interested in the really obscure attacks at this point, not the basics.

By my estimations we could see $100 transaction fees when bitcoin reaches $80K (based upon segwit only). Not sure what else I might be leaving out.

Sounds to me like the 1 MB block size is a Schelling point because of the network effect. Segwit 2X's failure seems to confirm this.

Andreas Antonopoulos seems to think that block size increases will happen anyway at some point into the future, but it's what he's not saying that I'm paying more attention to. 2017 seems to have been a major turning point in this field. Hive account@wstickevers had been talking about bitcoin on FB since about 2012. I had already heard about it but dismissed it as just another payment system back in Jan 2010 (due to my bankruptcy in Las Vegas I was looking at other methods of payment due to worry over losing my credit status). I think it was bitcointalk.org that I ran into in 2010, but not sure as my memory is not as good as it used to be.

My head was too deeply immersed in my own software projects until 2015 and in October I tried signing up for Coinbase as William suggested. Then was rudely surprised by the KYC and didn't want my driver's license on the darknet which I knew would eventually happen. Then I ran into a problem with the release of Delphic Oracle XPF (a memory bottleneck caused by dynamic creation of FMX objects after finally compiling in Nov 2015) which took me about a year to solve (about 100K lines of code rewritten). In late 2016, I started looking at bitcoin again, but still didn't "get it" until reading the white paper and finding out about Andreas Antonopoulos. I got in very early in 2017 and it just kept going up. Really wish I'd just gone all in back in 2010, but of course that would have included mining and nobody really gave bitcoin any chance at all or realized why it was important except for the really obscure nerds.
