I use copay, what's up ?
tho i don't claim to be an expert in it, i just made a simple wallet. It's made by the same guys who have bitpay which is a way for merchants to accept BTC for products (i like bitpay, i feel like they are actually doing SOMETHING to bring crypto to merchants)
You can link your coinbase which is kinda sweet, but i haven't found a way (yet), to import my priv keys (they use seeds and/or QR code)
