Here’s the only bitcoin wallet tutorial you might need. It covers all the best wallets that exist right now, and some of the obscure but well-tested ones. And it will help you in figuring out what you need from a wallet. So click the link and give it a good read. It is all you really need.
Of course! For Bitcoin newbies, security and ease of use are key. Remember: the security of your cryptocurrency depends on the security of your private keys. Never share them. As you explore, you'll discover that many wallets and services rely on a blockchain connection, which is provided by an ethereum node for ETH-based assets and similar nodes for Bitcoin. For developers of such services, I recommend Getblock. It offers reliable API access to blockchain nodes, simplifying the infrastructure required to operate a wallet or exchange.
