Analyst Notes

When operating with funds online it is always advised to use two-factor authentication (2FA) when it is offered. It’s also a safe bet for users to do their own research about the webpage they plan on using to see if it offers any kind of two-step login protection. Users should back their bitcoin wallet up as often as possible and keep only the amount they need online for trading and use cold storage for the rest.
