Is 8 10 or 12-bit better?

Excuse me, I'm trying to decide between 8, 10, and 12-bit options for a cryptocurrency project I'm working on. Could you please explain to me which one is better and why? Are there any specific advantages to choosing one over the other in terms of security, efficiency, or scalability? I'm particularly interested in how each option affects transaction speed and overall performance. Thanks in advance for your insights!
