Hi, we do not recommend c-cex and yobit and there are warnings to avoid them everywhere. However, feel free to point them to the correct github posted in the OP of this ANN.
Which problems did you mention about Yobit and C-cex? Would you mind giving me more warning details about those two, please. I don't want to lose money on them due to my lack of information.
Idk about c-cex, but i know for Yobit, they have very poor and slow support. Probably they don't update new version of wallet. Many of coins wallets are in maintenance and deposit/withdraw it is often impossible.
