Coinbase isn't the best choice because you don't have a access over your private keys. That's why like many users I prefer non-custodial solutions such as Coinomi, Atomic, Ownr wallet and etc.
Wrong, your reply would have been correct back then when it was Just the
Coinbase web interface and app (a simplified exchange and custodial wallet) and
Coinbase Pro, formally GDAX.com (Coinbase's advanced exchange).
I guess due to competition the brought a new product to the market, A wallet that's noncustodial and lets you have control of your seed phrases and private keys but it's only mobile based as of today and close sourced like many other wallets
https://wallet.coinbase.comVery few are
open source like
BlueWallet and
ElectrumAs I already wrote before I personally like BlueWallet but you are not being correct here.
First of all,
Bluewallet is a custodial solution (according to
https://walletscrutiny.com/android/io.bluewallet.bluewallet/)
This app was earlier classified as non-custodial but as their main selling point is their “Unfairly cheap and blazing fast transactions on Bitcoin” Lighning Wallet and that wallet is custodial without warning the user about this fact, we have to change our verdict although in summary the verdict remains not verifiable.
On the other hand, Electrum for Android is not open source (yet) but falls into the
not reproducible from the source provided.
