The reason why i outline that security is one the most important thing or objective that a beginner in cryptocurrency journey should know as one of the major key is that , my friend who bought a Bitcoin with the savings does not know that trust wallet seed phrase which some people called "private key" is very important, he bought a Bitcoin that worth two thousand dollars and he never knew that his seed phrase have to keep in secret and he wrote his seed phrase on paper and drop it on his table after two months he started looking for the paper were he wrote his seed phrase where he login his trust wallet and two thousand worth of Bitcoin in his wallet is not to be found, its there i noticed that security is highly important in Bitcoin and right now im of very observant and careful with any that concerns security mostly cryptocurrencies.i am a newbie and i will like to tell my fellow newbies to be security conscious of things that relates with Bitcoin because its a decentralized currency.
Security is important in every cases, no matter what investment you make physical or virtual, if you don't have good knowledge about security or if you can't make your investment security, then there is a high possibility of facing loss. Did your friend really not know about the importance of seed phrase? If not, why would he write it on the paper? Anyway, if there is such indifference, then this kind of situation has to be faced again and again.
Moreover, I would like to say another thing that only seed phrases or private key protection does not mean that you have been able to fully protect your fund. Because there is another issue here is that your wallet gets hacked, many times new users keep their funds on the device they browse unsafely, in this case, they are victims of phishing. So, to fully secure your fund, you have to turn off unrestrained browsing. Moreover, it is always better to use cold wallet for holding. You can visit
