Simply do not share your private keys and information to other people no other than yourself. If they won't know such information, your cryptos won't be at risk. Also avoid logging in your wallet to other devices. Hardware wallets are also another way to secure your cryptos but be mindful of not putting it to any place in order to double the assurance that hackers won't have a chance of getting your holdings without your consent, ofcourse.
One way of protecting my bitcoin is accessing trusted websites only. Another is by using hardware wallet or offline mode. In that case, it is far away from the internet. Hackers always finds a way to get your precious coins so it is better to get away your coins away from the internet. We must think what will they do so that we can prevent them and secure everything we worked for.
Websites that has credibility is also another way of securing your cryptos. There are fake websites which would scam your holdings if ever you won't be careful of your actions. Always check the site's credibility and reputation. Asking first is not expensive, and it could save your entire cryptoholdings.

https://cointelegraph.com/news/threat-alert-new-trojans-targeting-major-crypto-exchanges-apps-discoveredI am new to cryptocurrencies but I gained a lot from this news. We need to stay connected everyday to read news because cyber criminals are looking for ways to steal our coins.
A week ago, I read about the safest wallets, I found out that the safest are paper wallet and hardware wallet. The wallets are offline but to make a transaction, you have to connect it online. I later read of a malware that can steal cryptocurrencies from trezor or ledger nano in just 15 seconds which are the best hardware wallets.
So, we need to know how to manage our wallets too and have a strong antivirus to protect us from hackers and also we need to know the latest threats from cyber criminals so that we can protect ourselves away from them.
There is no trojan virus for android nor android viruses so I think it safe to use mobile application in saving cryptocurrencies. Another, I am not sure if it is true but I have a friend who told me that he bought a flashdrive that does not stores movies, songs, pictures, ms office files but stores bitcoin. If it is true then it is a really good way of protecting your crypto and keeping it away from the internet.
That is probably a hardware wallet. I know some wallets such as ledger nano and trezor and by far reading the feedbacks, these two are guaranteed to secure your holdings.
