I wasn't able to find the source code on the website (
https://coolwallet.io/).
Am i right in assuming that this wallet is completely closed source ? And that the customer has to trust a company (without much trust rating yet) to build proper hw wallets + code ?
190$ seem to be quite a lot. Especially since it almost entirely is made of plastic. And 2 hours charging for '20 operating cycles' doesn't sound that good either.
