What is the best methods to protect altcoin from hacker?
Anything on the web are vulnerable on hackers attack. This includes tokens and coins in our online wallets. But to get rid of it take some safety measures for yourself, first, dont ever entertain any email that contains links that maybe a phising site and also never ever let your private key known by other users or leave it unattended ( posting it in any thread or put it in wallet address box).
I keep the Altcoin I have by holding it. because I believe by holding Altcoin able to make Altcoin is safe. even able to increase the price to become more expensive again. so I am very lucky to hold the Altcoin that I have and make the price also increased. so I will hold Altcoin to secure and increase the price.
