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.
I gotta ways to go yet, before my portfolio is back in black.... but that's o.k. These are good signs - even though we may need to experience a few more bumps in the up and down road between $350 and $500, which is beginning to seem very doable within the next few months, if not sooner.
