The best Bitcoin wallet depends on the user so I think, there is no really general best Bitcoin wallet for the fact that all people do have different preferences on choosing their wallet which is good for storing their cryptocurrencies not just Bitcoin but also other cryptocurrency. All wallets do have their unique features that fits the different needs and wants of the people. So people are the ones who choose their wallets which fits to their needs and conclude that it is the best wallet to store up their Bitcoins. Well in my case the best Bitcoin wallet for me is the wallet that is generated by our country which suits all my needs compacted in one wallet wherein I can also store up BCH, XRP, and ETH.
