Not to single you out, but what you are doing is not investing. Depending on how one would like to frame things, it is somewhere between "speculating" and "gambling".
Nothing that is an "investment" returns 2.5x in two weeks, unless you believe that Madoff was a good investment adviser.
Do all the bitcoin you want, but do it with money that you can afford to lose all of. Nobody's going to ring a loud bell when the "market" for these securities suddenly goes to zero. Unlike assets with SOME underlying long-term value (land, inventory, patent portfolio), when the panic hits, it will be all sellers and no buyers, and to zero it will go.
