Thanks for the explanation. I thought I couldn’t use that crypto with Ledger. Is it risky to use a 3rd party app for my ledger? If I'm using myetherwallet for example, I have to share my private key with them, isn’t it? If it is, I guess that's risky.
As of others check also prokey or keepkey.
They support less coin then Ledger I guess. I had a quick check with keepkey and they listed only a sum of 50 coins if I'm correct.
