# Never use others computer or Public Wi-Fi to access your wallet or exchange always use secure connection
That's even a given, not just for one's wallet safety but for the general safety of other personal info on one's device. I remember using a hotel wifi on my PC several years ago while starting off my trading journey so as to save up on data. On that PC was just my FX trading app, nothing more. Cryptos weren't even a thing then. I was lucky nothing happened. I won't try such now, knowing what I know about the internet space.
# Never join any team views or others to learn any trading or use purpose for buy/ sell community
I don't agree to that, especially the first part of it. No man is an island. You've to belong to groups with same interest as you've. It helps one get relevant information concerning one's industry to ascertain where the trend is.
# Never join any airdrop from telegram group or social media
Airdrop hunters will have to decide that. Though that decision may be easy to make now due to how messed up airdrops have become. But of course, there's no project that doesn't utilize social media.
# Never buy sell btc BTC from any social media ( You can Use reputable/Verified platforms to buy/sell)
I don't know about others but the first time I sold BTC was on social media. In fact, it was on a WhatsApp group before the creator moved it to telegram. That was in 2017 and it was a seamless transaction. I'm still in that group till date and it has now grown bigger and better on Telegram.
#Never accept any SMS Based 2FA it will be swap your sim ( SIM SWAP ATTACK) so avoid any 2FA code by sms
Yes, never accept an OTP when you weren't the one who triggered it. Anytime you get an OTP you never requested, just know someone somewhere is trying to hack your account.
