Common Bitcoin Scams: How to Spot and Avoid them


Crypto transactions are a fast, hardly trackable way of transferring funds across the globe. That’s why this is such an attractive asset to “bad actors”.

At Coinnest Africa, we always go the extra mile to protect your funds and data, however, you should be exclusively responsible for securing access to your own account and assets.

In this post, we’ll tell you more about some of the most common scams and how to identify and avoid them.

How to spot a scam

Being cautious is always a must, and there are clear signs of scams that you can look for to expose them. Let’s remember red flags that may help you spot a scammer: 

  • Scammers’ offerings are too attractive. Getting easy money or doubling the profits? Too good to be true!
  • A scammer usually tries to mislead you. You are telling me I won some money, but have to pay some amount in advance to get the prize? Aha-aha! No way!
  • They speculate on your privacy. Send you an email with some sweet offer and a malware attachment. Don’t click on it!
  • They are short on time and try to create a feeling of urgency. The less time you have to think, the more chances to get into the trap.
  • They try to scare you. You can hear that something is wrong with your card, account, or computer and offer to fix it if you give them your credentials. A big no-no!
  • They are tricky. Pseudo-representatives of the company can ask for your personal information and payment details. Don’t trust them!

By avoiding these traps, you can better protect your holdings.

Now read more about the most popular ways scammers can use to hunt your funds and sensitive information. 

1. Phishing emails

Even if you are new to crypto, you have probably heard about the practice of phishing. It typically involves the scammer impersonating a company representative or support agent to extract personal data from you. They can contact you via email, social media messengers, phone, and fake websites.

Phishing emails are becoming an increasingly more serious problem, resulting in huge losses of funds. Basically, scammers masquerading as crypto exchanges or traders trick people into transferring money to them.

Beware of emails that are allegedly sent by the services you use and call you for urgent action. This could be the email to reset the password or it can be a link to start some sort of interaction with your account. If you didn’t ask for a password reset, why would you follow the instructions? If someone else was able to access your credentials and initiated this action — don’t confirm it anyway! By following the links in suspicious emails you help scammers to reach your funds.

You can find the difference between a fake email sent with the aim to hack into your account and a legitimate one sent from a company/service you are using. Just pay attention to the sender’s name and its domain name. Even a small typo in the email can indicate fraud. 

Emails from Coinnest Africa have the domain name at the end of the sender’s address. For example, emails from,, and any other emails from the domain are legit.

That link in the fake email will mostly redirect to a fake website – similar to the original one – that will prompt you to log in. This way, the attacker can get access to your account.

2. Fake social media pages 

If you’re following celebrities on social networks, you have probably seen many fake pages and accounts-imitators. The same applies to cryptocurrencies and exchange platforms, where malicious, impersonating pages are rampant. How to differentiate a fake account from the official one? It is a good idea to check:

  • The spelling of the account name. For example, fraudsters can use, which is similar to But having looked closer you can see that it’s 0 (zero) instead of O (small letter “o”).
  • Account URL address. Impersonators add extra symbols, letters, or misspell the official name of the company. The URL address of the legitimate social page should contain the official company name only.
  • Date of creation. A fake page is usually created recently.
  • The content posted on the page. Repeated spam messages with the same link is a bad signal.

Now you know how to identify a fake page. Should you respond to the sweet offers that come from suspicious Twitter or Facebook accounts? No way! If someone asks for even a small amount of cryptocurrency, it’s a 100% scam!

3. Direct messages in social networks

As we found out, scammers are not ashamed to impersonate prominent cryptocurrency company accounts on Facebook, LinkedIn, and Twitter. They’ll try to contact you in direct messages so no one of the official company representatives can track their actions and report a scam.

A common Telegram scam sees the “well-wisher” lurking in official groups for crypto wallets or exchanges. When users report a problem in this group, there is a high chance that a scammer will reach out privately. They will impersonate customer support or team members and offer to “help”.

Remember, no one in the team will ever ask for your account credentials, password, or so. The most prudent course of action if you receive an unsolicited communication is not to engage at all and check the authenticity of any social network page or message you receive by writing to the Support Team via official channels.

4. Fake websites

Even if you stay away from the suspicious links in the emails, you may accidentally bump into a fake website by simply searching for an official company site.

There is a surprising number of websites that have been designed exactly like original official company websites to confuse users.

How to recognize them?

Find a small “lock” sign in the address bar near the site name and click on it to see the security certificate and the issuing institution/organization. It is a sign of a secure connection and one of the proofs of the legit website.

Even if the site looks identical to the one you think you’re visiting, you can be directed to another platform for payment. Be attentive!

Some security tips to follow:

  • When in doubt about a message you have received, ignore it and contact the Support Team via official communication channels.
  • Double-check the URL of the websites you’re visiting.
  • Bookmark your frequently visited sites. Search engines can mistakenly display malicious ones.
  • Keep your password safe! Nobody else needs to know your 2FA code, withdrawal pin code, 3DS code, private keys, or seed phrase.
5. Fake giveaways

Cryptocurrency giveaway scams have been a problem in the crypto community since the last major bull run in 2017. In fake giveaways, you usually need to send a certain amount of cryptocurrency to a giveaway address before you “get the reward”.

Scammers promise to double your funds after that. However, that never happens. The cryptocurrency transactions are irreversible, hence, once a victim sends money to the scammer’s address, there is nothing anyone can do to get them back

6. Malware

With the help of malware, hackers can get the passwords needed to access computer networks or info about credit cards and bank accounts. Nowadays, malware can be also used to access cold crypto wallets.

You can accidentally download malware by clicking links in phishing emails or on fake websites and social media. There might be a post, for example, where someone offers a certain program that allows you to mine cryptocurrencies for free.

Some malware programs change the crypto wallet addresses when you paste them from a clipboard. As a result, instead of sending crypto to your wallet, you end up transferring it to someone else – and it’s gone.

When transferring crypto, always be sure to double and triple check the recipient’s address.

It’s a good idea to be super-cautious about what programs you allow to have administrator access on your devices. An up-to-date, reputable virus scanner can also help but is not foolproof.



At Coinnest Africa, we care about your account and funds security as much as you do. However, this is not a single-player game. If you give someone access to your account or accept sweet offers from scammers, you literally give them the key from the doors to your house.

However, Coinnest Africa implements the highest security measures to protect users’ accounts and their funds.
