Never heard of Peter Brandt,,, sorry to say, but I never care if it is him or Tom Lee or whatever trader is out there, all these guys say these things to try and manipulate the market, or to earn some money for shilling something else.
I have XRP but purely to speculate, if it goes to 20 cents I will probably never buy anymore but if it goes even lower I might even add more. But I know I might lose it all.
