Coin Circle Security Rules (1) Many people spend a lot of time researching how to trade coins, but never think about how to protect them. In the world of cryptocurrency, your enemy is not the bear market, but your negligent self. 1/ FTX taught us one thing: Not diversifying currencies is called risk control, you also need to diversify the platform. Buying BTC at the same time, if you are all on the same exchange, it is not a form of diversification at all, but an all in risk. 2/ So the first step is that your coins should be distributed across different exchanges: One copy from Binance, one copy from OKX, and one copy from Coinbase. The more platforms there are, the better, but there should be choices and backup. 3/ More importantly, emails should also be dispersed. Please register with different email addresses for each exchange. Binance uses one set, OKX uses one set, and Bybit uses one set. This can reduce the risk of overall account loss of control. 4/ Email alone is not enough, and each password needs to be unique. Use password generators (such as 1Password, Bitwarden, lastpass) to generate independent strong passwords for each email and each exchange. Don't use your dog's name and birthday set. c'mon. 5/ Cold wallets should also be decentralized. You shouldn't have only one cold wallet, let alone just one mnemonic backup. Please backup at least 2-3 copies of the mnemonic words for each cold wallet and store them in different secure physical locations. Please also copy 2-3 copies of the cold wallet. It's not that I'm afraid you'll be stolen, it's that I'm afraid if you fall into a ditch, even my cold wallet will follow me. 6/ When it comes to computers, do you often use one computer to play games, watch movies, connect randomly, and then use it for trading? Please separate. A clean computer equals a safe computer. You can consider using a dedicated computer solely for trading, or even dividing it into a dedicated DeFi interaction machine. This is the basic operation. 7/ Mobile phone numbers should also be assigned. You should have at least 2-3 door numbers specifically for 2FA use. All exchanges require you to set up 2FA, so don't be lazy. Your phone is the key to your identity, losing it is like a wallet falling into a volcano. 8/ And most importantly, you need a complete Recovery Plan. Just like the company has a fire drill, the cryptocurrency industry also needs it. You should simulate a 'worst-case scenario': Twitter stolen, exchange locked, computer broken, cold wallet not found What should you do at this moment? 9/ Do you have an emergency contact account? Is there a record of recovery/setphrase? Do you know where to store your backups? Is there anyone you trust who can help you? These are the keys to your survival. 10/ Most people spend time searching for 10 times the amount of coins, but don't spend any time preparing a script for 'what if they wake up tomorrow and it's all gone'. But true veterans know: The most difficult thing is to keep the principal and survive until the next wave.
