I would like to introduce myself, since my boss has been so busy he didn't think of it - I am the new lead blockchain engineer/dev in the project now.

True

Sorry to all on that ... I am without excuse

Beside many things questioned here one is sure, the whole system will be writen in GoLang. Everything in our project will be GoLang at end.
+1 to that. Sadly Cryptopia sees forks as new coins and Yolobit isn't keen on updating wallets and listing new coins.
It is not like that. Many people are confused with meanings of that "fork" word.
I think for Cryptopia as long as blockchain is same all updates on a wallet are ok, even it is rewriten to another language. Yolo is out of any talk.
