The growth value of crypto-valves has enriched many people, but also left room for more hackers and fraudsters to get used to abusing the technology behind them
One of the scams you need to look out for in 2018 is cryptojacking, which happens when a website or Wi-Fi network will "steal" your computer to "dig" bitcoins in the background. Only one computer that digs can not do much, but the whole network can quickly spread over the Internet and quickly find bitcoins.
Though it sounds like something that could not be a reality, however, kryptoningking can seriously damage your computer or smartphone. This malicious software uses so much of your device's performance that it can overheat the processor, or at least make it slower because a hacker is running in the background to find bitcoins for himself.
But all this can be preventively avoided by installing software that will help you not to attach harmful software for encryption.
For now, the best option is to use the ad blocker of the Opera browser. Earlier this month, Opera introduced the update that received their ad blocker, which will now be able to block malicious software that attacks the device in order to "cry" crypto.
If you do not want to switch to Opera, there are unofficial softwares that have the same function for Chrome and Firefox. Some of them are Mining Blocker and NoMiner, yet the most effective protection is provided by Opera.
Considering how many actually willingly mine cryptocurrencies on their own computers, I doubt it is a serious harm to your hardware, since the temperature sensors will just cut power or increase the fan speed once the processing units get too hot, but it would indeed be annoying to have 100% of your CPU power directed at making money for someone else.
