One day you will go to Steemit.com and there will be a 404 Error with a message saying sorry, we will be back shortly. That day will never come, they will blame a hacker breach for losing all of your money, and that will be the end of that. It's really a shame but it will happen, it's happening with many others today and it will continue to happen.
If you don't want to lose your money, take it out now, unless you already lost.
