Thanks for adding the translation to OP, Porf! But I think its ticker should be [BEN] instead of [BAN]. At same time, I think the term "Bangla" from OP should be replaced with "Bengali" (maybe Learn Bitcoin can confirm that).

I also compiled below a list with what translations are needed for our remaining topics in progress.

• [Education] Bitcoin Privacy and Anonymity by Husna QA and DoomieChikito: [POL] [RUS] [FRE] [TUR] [ITA] [FIL] [ARA] [HIN] [POR] [PID] [BEN] - so this should be in attention of cygan, zasad@, LeGaulois / paid2, mindrust, Ale88, Baofeng / Yatsan, Kavelj22, amishmanish, gagux123, Hatchy, Learn Bitcoin / DYING_S0UL
• There are 2^256 private keys out there: how big is that number? by fillippone: [FRE] [TUR] [ITA] [FIL] [ARA] [HIN] [POR] [BEN] - so this should be in attention of LeGaulois / paid2, mindrust, Ale88, Baofeng / Yatsan, Kavelj22, amishmanish, gagux123, Learn Bitcoin / DYING_S0UL
• Campaign to improve posting quality for local boards^{READ BEFORE TRANSLATING!!!} by 1miau: [SPA] [FRE] [TUR] [ITA] [FIL] [ARA] [HIN] [POR] [IDN] [BEN] - so this should be in attention of Porfirii, LeGaulois / paid2, mindrust, Ale88, Baofeng / Yatsan, Kavelj22, amishmanish, gagux123, Husna QA / dansus021, Learn Bitcoin / DYING_S0UL

So there is a maximum of 47 translations which can come out from the above topics, in case they will be translated in all remaining languages. 47 translations - that's a lot! Perhaps we can wait a bit more before proposing other topics and pushing a bit on these remaining translations? (I didn't include above Greek language since, as far as I know, BlackHatCoiner stated from the beginning he does not have time for doing free translations.)
