"cheaper (eventually) hardware"
Best case 2-3 years from now. Otherwise it will take a major global recession to get us anywhere near last year's prices.
"the US has become an unsafe place to keep your data"
I empathize with this but curious what would make any other country a better safehaven for your data? I personally like the EU's approach to data safeguards, but are there other locales/data protections you have in mind that would keep your data "safe".
Careful about data distribution/licensing as exchanges have explicit data distribution clauses with Yahoo. If you got permission through Yahoo you're all set.
