Never use your main wallet with all your crypto for anything. It is not worth the risk. Create new wallet for whatever you want to do (buy, sell, use some site etc.).

I can't understand why so many people risk their crypto like last fools by using their main wallet. If you have thousands or even tens or hundreds thousands dollars in wallet stop the fuck using it for anything. It is your treasure chest, your safe. No smart guy walk with their safe, with $100k inside, on their back to the shop, they instead use wallet with few hundreds inside. No one smart use their main bank card with all their lifesavings to pay for groceries or online shopping (if you do so also stop). So why are you using your main wallet?

In crypto where you can for FREE create unlimited amount of wallets you have no excuse you lazy gambler. If anything bad happen, phishing site, evil contract you will lose everything and no amount of crying will turn back time.

Your main wallet should be be hardware wallet with just BTC and ETH probably, but that's beyond the point. Even with software wallet rule stay the same. Keep max 5% or 10% of your crypto in wallet you use. If you want to do something really stupid transfer enough crypto to brand new wallet. Crypto you HODL is non touchable at all. Probably also should be divided between few wallets just in case. Better lost 25% or 33% of your holded crypto than all, right? You have no excuse to be irresponsible beyond laziness. Creating new wallet and writing down seedphrase is less than 10 minutes of work.

Stop begging hackers and scammers to steal all your crypto at once. Don't use your main wallet for everything it is not safe. Crypto is about decentralisation, by having just one wallet you are not much better than bank, one wrong contract signed and you will never forgive yourself for losing all your crypto.

Your main wallet can be used only to transfer crypto to your other wallets or to exchange. Nothing more. Less you interact with it safer it become. Safe in homes of rich people are hidden, under carpet or behind painting, your wallet should be hidden behind your other wallets.
