The 3 Best Cryptocurrency Exchanges

1. Coinbase
Coinbase is the largest crypto exchange, boasting over $20 billion in trading volume and over 10 million registered users. The exchange offers access to ethereum, litecoin, bitcoin, and bitcoin cash. It was rumored that Ripple would be available on the platform early in 2018, but the company has stated that it has no such plan. Coinbase also provides an active trader platform known as GDAX that has a plethora of features and analytics for short-term crypto investors.

It is relatively simple to set up an account and buy your first cryptocurrency on Coinbase. The exchange is one of the very few that allow the purchase of cryptocurrencies via U.S. dollars.

Your account is set up by clicking on the "sign up" button on the upper right-hand corner of the site. Next, you fill in the requested personal details and agree to the user agreement, and click the "create account" button.

You'll then need to verify your email and choose your account type. Most of you will pick individual account unless you decide to own your crypto in another entity like an LLC.

Everything seems normal so far, but this is where crypto exchanges start to differ from traditional online stock broker s.

You will be asked to enter your phone number. This is not so the exchange can call you to suggest upgrades or sell it to a telephone solicitor, the reason is far more important. Your phone number is used as a two-step authentication security system to help keep your account safe. When you log into your account, Coinbase will text a code number to your phone that needs to be used to log into your account. Your username, password, and text code create a strong barrier against hackers accessing your account.

Next, you will be asked to confirm your identity via uploading a photo of a passport, driver's license or photo ID.

Finally, connect your funding method, which can be a bank account or debit/credit card to your new account. Funding methods are verified by Coinbase via a small, refunded charge to your account.

Now you are ready to make your first order!

2. Gemini
Gemini is an exchange launched by the Winklevoss Twins of Facebook fame. The account setup is very similar to Coinbase, but the exchange is not available in some states .

While you can only trade bitcoin and ethereum on Gemini, the exchange provides FDIC insurance for cash balances. This is rarity I consider a huge positive in the world of cryptocurrency sites. Unfortunately, there is no insurance once your cash is converted into digital assets.

3. Kraken
Kraken is a true digital currency exchange offering 17 different cryptocurrencies for trading. There is a three-plus level approval process with each level more onerous than the last.

The first two levels are very similar to the steps of the above exchanges. Being approved for level 1 or level 2 allow full use of the exchange, but there is no funding via U.S. dollars. You need to transfer to cryptocurrency from your wallet or another exchange to make trades on Kraken.

Reaching the third level requires all the steps for the first two exchanges plus a selfie photo of yourself holding a handwritten sign with the date and "for trading cryptocurrency on Kraken only" on it. Doing this reminded me of most wanted criminal flyers at the local post office.

What I like about Kraken is that if offers the red-hot currency ripple. There are very few exchanges offering ripple that also accept USD, making Kraken one of my favorite exchanges.

Risks To Consider: Out sized risks exist in every concurrency and exchange. Only use money that you can afford to lose when investing in concurrency. Think of crypt o investing more like speculation than true investing. Along with the high risk, huge gains can also be made. In the crypt o world, risk truly does equal reward.

All online wallets are so-called hot wallets, and unfortunately, they’re not the safest of all.

Why?

For one, they’re centralized. It doesn’t really make sense for crypto-enthusiasts to promote the hype of decentralization and then storing large amounts of digital cash on a centralized online wallet.

Secondly, like any other website, they’re prone to be hacked. If money is involved, that’s usually good enough reason to try to compromise the security. And if funds can be transferred out to an anonymous address without the possibility or reversing the transaction, that’s even more of a reason to hack.

Solution

There’s not much you can do. Every one has to use a hot wallet every now and then. However, they’re not meant to store large amounts of coins for extended period of time.


#1 - most secure method

It depends on an individual, but I like to think that the most secure way of storing your large amounts of coins is a paper wallet.

You can make a few copies of it, laminate it so the paper doesn’t deteriorate over time, and lock it in a safe, bank or dedicated security deposit box.

However, the best option is to combine both the method #1 and #2.

This way you have access to your coins on a short notice (if you decide to lock away your paper wallets a few miles away from you in a deposit box) because you are in possession of your hardware wallet.

And if you lose it, then you can always revert back to your backup paper wallets.

#2 - even better method

There are certain hardware wallets that are way more secure than the above two methods. For example, a Ledger Hardware Wallet will store your coins securely, because it’s not connected to the internet, therefore, it can’t be hacked.

The downside to hardware wallets is that you can misplace it and then ultimately lose it. Once lost, given the fact that you haven’t written down your private keys somewhere say, you have no access to your coins.

The upside is that these hardware wallets are nearly indestructible, so you not need to worry about breaking them.

#3 - a bit more secure method

Desktop wallets are considered to be more secure than hot wallets. The key word here is considered. That’s because it depends on your level of understanding how secure you can make your computer to be.

If you make it really difficult for a hacker or malicious malware to penetrate your computer, then sure - on paper it is more secure.

In reality, the vast majority of people think that one antivirus software and a system firewall are enough to prevent any security breaches.

It’s probably best to get extra education on security before one decides to store a lot of coins on one’s desktop.

#4 - least secure method

You can engage a 2-step verification process for most hot wallets and use Google Authenticator or Authy to generate access codes. Whilst this isn’t a solution, it puts another layer of security and makes it tougher to breach.

Although, sometimes hackers aren’t the problem. What if the hot wallet company goes bust or they lock you out of your account preventing you from accessing your funds?

Hot wallets are the least secure methods of storing your coins.

Summary

As you can see, it all depends on you and the amounts of coins you plan on storing. It might sound scary, but this is the reality. It’s best to be safe and take that extra step than to be sorry.

Good luck!

No. 1: Paper wallet or other cold storage. A paper wallet is simply a document that contains all the information you need to generate the bitcoin private keys you need. It often takes the form of a piece of paper with a QR code that can be scanned into a software wallet when you so desire. By storing your bitcoin offline, trusting nothing and no one but yourself, and you have all the information you need to control and access your bitcoin, you're using the strongest "cold storage" method out there.

No. 2: Ledger or Trezor (hardware wallets/dongles). When you start thinking about using hardware storage solutions for your cryptocurrency, you know you've gotten serious. These dongles both make the best bitcoin wallet list because of their safety and mobility. Plus, they're good enough for professional investors.

No. 3: Electrum (software wallet). Electrum is a popular, free storage option in the bitcoin community, and is one of the most, if not the most, well-respected desktop storage apps out there. It's been around since 2011 and is also available for mobile, though Apple Inc. (Nasdaq: AAPL) users are out of luck – to date it's only supported by Android.
Electrum gets high marks for its ease of use and user interface, which is always nice, but the real reason it's the best bitcoin wallet for desktop is its safety and reliability. Like any desktop wallet that's worth its salt, users get to control their private key; Electrum doesn't know what it is. Since your private key, a long string of letters and numbers, gives you access to your bitcoin, you need to keep that, you know, private.
Many online wallets and online exchanges don't give you ultimate control of your private key, adding an extra layer of risk. You have to both trust the counterparty is a good actor, and hope their servers don't get hacked, if that could compromise the service or your information.

No. 4: Blockchain.info (online wallet). Exchanges are ripe pickings for ambitious hackers. Web-based wallets can pose some security and hacking risks too, but they don't have quite the glaring target on their backs that exchanges do. Nor do they have the nightmares of Mt. Gox and Bitfinex hanging over them.


No. 5: Coin base (online exchange). Online exchanges are, by and large, less secure than the methods described below. But Coin base seems to have learned from the lessons of its predecessors, and is one of the biggest bitcoin exchanges in the world. It's also user friendly; not only can you buy, sell, exchange and trade bitcoin on Coin base, but you can store your bitcoin in a wallet there, too.
