Trading View allows you to create an account where you can save your charts. If you choose you can just enter your zip code manually. We are not saying that all deposit exchanges are scams, but simply that there is more risk when you use this type of exchange. Follow this post. Prefer those exchanges which offer proof of reserves for client Bitcoins, regular external audits for client fiat funds and have a long history of secure, ethical operation. Credit card buys are often instant. Kraken’s fees are quite confusing.
