What would you recommend I use instead as a reliable and hassle free alternative for the next couple of weeks until my cold wallet gets here? I'm looking for something that's both reliable and won't take too long to set up/require identification/etc.
It looks like Guarda wallet is mainly closed-source. Only certain components are open-source, not its core wallet. In which case, you might want to consider other alternatives.
What cryptocurrencies do you have, by the way? The most reputable hot wallets I know are normally Bitcoin-focused. Are you open for maintaining at least 2 wallets? Electrum and Mycelium, for example, for your Bitcoin and certain altcoins, respectively?
By the way, what will happen to trading efficiently? Would you be taking out your coins every filled order? That would be costly.
I'm actually invested way more in ETH than I am in BTC.
