Yeh i think youre right, the thing is IDAX keep saying they will recover it but then dont respond to live chat, they havnt answered none of my email tickets, Why cant they just tell me its not able to recover.
Bad customer service?

Do you know what Nexty NTY is if it isnt an ERC20 token? How would i go about storing this on my nano ledger?
Like I said... it is essentially just another cryptocurrency... like BTC, BCH, ETH, DOGE, LTC, BTG, XRP etc... As for storing in a Ledger, basically you can't unless Ledger decide to implement support for the NTY currency. I don't think it's likely, but you never know. Maybe write to Ledger support and see if they plan on implementing support.
