Capital and currency controls may backfire, accelerating the move into bitcoin. While the volume of P2P bitcoin trading in Sudan is at a trivial level, that volume can rise quickly if exporters in Sudan discover bitcoin (as the only remaining method for them to send payment without needing to transport cash and gold across borders) and then can justify paying a large enough premium for those bitcoin that it gives incentive for foreign currency conversion vendors and others to try and acquire bitcoin in any manner possible. (so as to sell for the premium that the exporters are willing to pay).
