After starting buying bitcoin in September 2013 at 130$, all the way up to 1200$. Then accumulating further all the way down .... if it keeps the pace I will finally reach break even in about .... 10 minutes

Same here, bought from $800 all the way down to $200. Now nearly at break-even again. I'm fine with a slow rise, but this is ok too.
every parabolic rise is followed by a crash. If you want bitcoin to gain real value you want to have a steady slow growth developing.
