Currently, several online services have been created to detect fraudulent websites and services. Badbitcoin.org is an example. This is considered a trusted site, which provides a full list of fraudulent or verified frauds. Another service on @thatsascam on Twitter is also quite useful. This is a bot that detects spam. These bots check those virtual tracker accounts based on the retweets rate. Take advantage of such tools to minimize the risk of fraud.
I think the way to avoid hackers is to Know What You Are Facing, Avoid Unrealistic Offerings, Beware of Phishing Web Pages, Beware of Fake Digital Wallets, Beware of Bitcoin Steal Malware, Be Careful of Ads from Google, Separate Daily E-Wallet Computers from Computers.
