Its all relative, in some countries they have no proper access to stable paper money. All they have is dollars which in some cases have to smuggled as its seen as avoiding tax to use the currency of another country. Dollar itself has an ongoing failure to retain value that might get worse. Bitcoin relative to that has a fixed schedule of issuance and is only subject to fluctuation in retention by its holders, the actual amounts in circulation is not suddenly shooting up to aid some central party and their bills
Yes is the answer, Bitcoin can be a positive to a country suffering from problems in trade. Its not unknown for a people to be forced into barter trades with no divisible value available reliably. Bitcoin by gift anyone in the world access to an open ledger is enabling the worst off to continue to be part of a wider economy not boxed into a corner by local politics or trade problems. That is so incredibly valuable to poorest and I hope Bitcoin continues to focus on providing efficiency and cheap access to the poorest people, obviously this does rely on basic technology being available but even 2nd tier nations can have problems so my answer is a definite yes
