Thanks for the input on wallets! I've been doing quite the research myself.
What I find most interesting is that even Coinbase, although it actually says the word wallet in their description on the App Store, is not a true wallet in the sense of controlling the keys.
Obviously, that makes a huge difference...as we are seeing here now.
Yes, and I have stopped using Coinbase altogether! Centralized systems are really bad, I'm learning. I switched to just using the BitPay gateway for US dollars, but even with that Bitcoin wallet, I removed them. It's hard figuring out what is what right now.
