As long as some countries recognize bitcoin, it won't be going away. The problem isn't that the three largest countries are good at coercing smaller countries to follow suit so if those three agree to stamp it out we might have a problem.
My approach doesn't really change regardless of the happenings in the world. Keep powering up my sp at a rate of about 80% and keeping about 20% into steem so it's easily convertible to bitcoin or usd or whatever other currency.
Your plan seems very reasonable and sound to me!
