Hello guys! which site is the best for using bitcoin.

But i have account in two sites. But i don't know which site is the best. which site you like most. But most time i think Coinbase is the best. Because it has three coins of addresses. Such as Bitcoin, Ethereum and litecoin.

Blockchain is a better wallet in my opinion because you have the ability to sign messages when needed and you can import and export keys to another wallet with ease and there are fewer restrictions with the wallet as compared to Coinbase.
You're absolutely right. If placed against coinbase.com, blockchain takes the lead in terms of security. However, that isn't to say that blockchain doesn't have its own issues. Also, coinbase is discriminatory with its services as some countries are banned from using its services even after registering on its network.
