Where is the safest way to create a bitcoin wallet?
In a trading site. It's safe because they have anothwr layer of security which are more likely 2fa authenticator or sms message which is impossible to break if you're very careful with your actions.
Your bitcoins will run away with the shopping site .. ahaha
Yeah just because a site has 2fa or things like that doesn't make them invulnerable to attacks. High multilayer security on the exchange wallet end helps, they do this by keeping the majority of their coinsupply in a cold or "offline" wallet. Only bringing enough coins online to process the withdrawal requests as needed.
