1. Do not engage in deep conversation with stranger who is only interested asking you about your total bitcoin holding or even regularly asking you about the platform you invested.
It doesn't make any sense to disclose the amount of bitcoin you are holding, the bitcoin you are holding is your secret, and it should be known only to you. Don't share it with people. Even people you see physically shouldn't know the amount of bitcoin you are holding in your wallet, not to mention a stranger whom you know nothing about. So even if you are encouraging people to invest, never tell them the amount you are holding, no matter how they force you. Don't tell people what you are holding just to convince them to invest in bitcoin.
2. Do not be fooled with their sweet words where they keeps asking you to invest and make money your interest within 24hrs to gain about 100 percent of your investment. Note; this is purely scam otherwise no other investment platform or anyone to be trading and giving you back 100 percent of your capitals.
Anyone asking you to invest in a specific platform, and you will be earning a specific amount of money within a specific period of time without any risk attached to you, is just trying to scam you. Whenever you see posts like that, just ignore them. If a platform like that is real, they will never share it with people; they will only invest alone.
If you want to invest, then get yourself a non custodial wallet, accumulate your bitcoin, and never invest on any platform.
3. Sets your telegram account where someone from same group can't contact you because telegram is the head of scammers, they can clone or impersonate someone you know and scam you without the knowledge of the real person.
Telegram is just full of scammers. I never respond to any message I receive on Telegram because I know the messages are from scammers, people asking you to invest in a specific platform, once providing signals, and once asking you to claim an airdrop. So I don't just disturb myself by replying to any message from Telegram.
5. Do not connect your wallet directly to any site you are not sure of otherwise you could be piped. The best advise is to always make a new wallet and send few gas fee to that wallet and keep your real wallet secure and safe from alteration.
Most people that do connect their wallets to random websites are the ones who are hunting for airdrops, they don't know that a higher percentage of airdrops are just scams. I don't really encourage people to participate in airdrops, but if you will, then always create a new wallet and never connect the wallet where your investment is to any website.
6. Do not create account in any website with the same password you used in another website that is so important to you, lets for example bitcointalk and other forum do not use same password you never can tell what would happened since you don't control the platform by yourself. It's important to always use separate passwords.
You have really given nice advice, it's not applicable to only password, if you have multiple gmail accounts, then always have at least one gmail account that you don't use to register for things online, that should be your personal gmail account. Don't use your personal gmail account to register for things online, and you can also use different gmail accounts to register on different websites with different passwords that you know you won't forget.
