Regarding the first question: We will definitely do our best to get Toa listed in more platform but for currently we will be staying with these exchange that we listed on.
The 2nd question: We can't comment too much one this as this depends on Cryptopia side, but we truly hope that I works back and all of you who trade there could get back your Toa Coin.
Buy in November when it was low, when I got the ledger nano pass all the coins I had bought in etherdelta ledger, for me it is the safest to have our coins protected.
