So if we shouldn't be leaving our coins on coinbase, where do we leave them? A full wallet is not an option for many of us. I don't want to have to download 100's of gigs of data just to store my coins... I even tried to move from bitcoin to etherum since I thought that wallet might be smaller. And it was, but after leaving it running for 2 days it still had a ways to go and all the IO it was doing was really trashing my SSD. At that point I looked into hot wallets like jaxx. But then on /r/jaxx, there were many people complaining about using jaxx only to have had their private keys stolen. So at that point I just left everything on coinbase :/ Is there any decent hot wallet out there or anything else?
