How possible can that be, Are you talking of months or years? I will not condemned your speculation but it seem you take it too far sir. Maybe you were trying to said $6 which I think ripple cannot achieve before end of next year! It is currently trying to get to $.5 and we are already in July.
First of all this picture is not by me. And yes I was also thinking like the same. 60 is too much but it could probably reach around 5-10 $ If BTC rise higher than 20k
With that amount maybe it can reach that but from the graph you shared I think it's really far being touch, though it's centralized market so anything can be manipulated who knows banking institutions will probably play and take the charge maybe it can happen, but then again it will be a huge amount of investment and a big risk to gamble.
