Ok, after some tryies of wallets that allow trades like:
exodus
atomicwallet
coinomi
...
They all use partners that says some kind of "KYC can be requested and money can be bloqued". Like changelly or similar.
I tried Bisq,
looks really promising, If I understand it well, you have a new kind of wallet called Bisq that have trade features between other wallets. In order to trade I have to create an ETH account on Bisq, transfer ETH from my cold wallet to Bisq ETH account, trade for BTC on Bisq and then, transfer BTC from Bisq to my cold storage.
Now there is low volume on BTC/ETH and others, but sure this will come bigger if this really works and ETH/BTC goes closer or higher than 0.1
Seems amazing, any other have experience working on bisq?
