To avoid the activities of hackers we should regulary check our assets and if we find that out asset are missed then we should change whole details and place of our remaining coins. All processes of cryptocurrency are taking place online therefore there is a great chance of hacking. Some people are unable to buy crypto coins therefore they are in Struggle to hack the wallets of other holders during Bull season because during Bull season market price higher and hackers always think to get profit from Bull season. People are often afraid of hacking so if this process last longer then no body will trust cryptocurrency and will move towards another way of earning.
We must do things right from the beginning so we are not hacked, a great deal of those that lose their coins either leave them at exchanges and other online wallets, fail to secure their seed words, install pirated software or access websites that could contain viruses and other malicious stuff, if you can avoid those and other common mistakes then your coins will be reasonably secure, and I say reasonably secure and not completely secure as no system can ever claim to be completely secure.
