You can always choose to have a tx confirmed in 10 minutes if you choose to pay the appropriate fee.
"difficulties in conversion at both ends."
You are really stuck in the mindset that one "must" convert to spend coins. But as Bitcoin adoption increases there is less and less a need to convert it. Example: my brother in France sent me BTC and I spent it instantly in the US at NewEgg, a retailer who accepts BTC.
"The Venezuela case is made-up BS"
It's real. Yes journalists exaggerate on how much Bitcoin is used. But it is growing, and quickly: https://coin.dance/volume/localbitcoins/VEF
"Instead, they lose it in volatility"
Statistically, volatility (which has been greatly decreasing by the way: https://mobile.twitter.com/lsukernik/status/8649208737189519...) causes users to lose money half the time and win half the time. So, meh, not a real problem. It averages to zero. On the other hand traditional remittance companies screw you over every single time with a fee averaging 7% worldwide (https://remittanceprices.worldbank.org/en). Clearly I prefer my brother sending me BTC than using Western Union.
Unless bitcoin transactions are clogged this week, and ignoring its extreme volatility and difficulties in conversion at both ends.

The Venezuela case is made-up BS, and the same for slotting in some other country. Worked example: https://news.ycombinator.com/item?id=14552819
> Sending remittance to family overseas without 10% wasted in fees.
Instead, they lose it in volatility and delays, and the difficulties cashing out at the other end - the latter was so bad for rebit.ph that they literally had to start an exchange just to have enough pesos on hand.
You're reciting cut'n'paste talking points that are largely refuted, like a Gish gallop in a single paragraph. This is not good argumentation.
