Is binance still the most safe exchange to keep coins in? I would say coinbase is probably number 1 is?
Big exchanges don't mean that they won't be attacked despite of how good their security methods are. Attackers spend most (or all) of their time to find methods to attack exchanges and steal money. Even big exchanges, themselves, won't be able to guarentee assests of their customers. In reality, crypto investors whom store their assests direcly on exchanges should know that besides security methods provided by exchanges; they should (have to) secure their accounts, their assets themselves:
- Strong passwords;
- Activate 2-factor authentication for their exchange accounts;
- Activate 2-factor authentication for their emails that used to register exchange accounts;
- Avoid or minimize cases when they use mobile devices to trade or log in their accounts;
- Have as healty habits on Internet space as possible;
- Allocate funds to secure their devices with AV softwares.
I meant doing this will help investors to build two-layered security for their accounts and their assets.
