# Quiz 10 Why does Bitcoin use Base58 instead of Base64 for encoding? (Choose all that apply) **Add answers and select the correct ones** * [x] To avoid ambiguous characters like 0, O, I, and l. * [x] To ensure the encoded string is easily readable and transmittable. * [ ] To include non-alphanumeric characters like + and /. * [ ] To make the encoding process faster. \ **Note to learners** "In other words, since Base58 avoids using non-alphanumeric characters (+ and /) and ambiguous letters (0 - zero, I - capital i, O - capital o, and l - lower case L), it helps ensure addresses are readable, transmittable, and more secure."
