The bitcoin world has gotten a little crazy, as you've probably seen, and the questions got so overwhelming that we decided to make it "blockchain week" here at Stock Gumshoe last week, solving as many of the cryptocurrency-related teasers as we could. 

The first one, and the most-discussed on the week, was David Gardner's "backdoor to bitcoin profits" pitch... curious to see what the Motley Fool is teasing?  Our story is here.

Next up was a pitch was from Jeff Brown for his Near Future Report, and to lure subscribers he's hinting at two investments that his tech connections are giving him as ways to invest in the revolution that blockchain will bring.  So what's he talking about?  Well, we might have to resort to some guessing this time, but the Thinkolator results and some chatter from me are here.

Next up was Matt McCall from Investorplace with "the safe way to profit from the bitcoin bonanza" ... that sounds like what we're all looking for, right?  So what's his secret?  Click here for our thoughts on that one.

And then we went Down Under to check into a pitch for our beloved Aussie readers, Ryan Dinse is pitching three stocks to benefit from the "blockchain collision" and the Thinkolator's got some answers for us to discuss here.  

We also unlocked an older teaser solution from the Friday File, since the folks who aren't asking about bitcoin are often asking about cobalt... that older cobalt teaser solution from a Casey ad is here.

Finally, I closed things out with the new Friday File for this week... which, naturally, had some more blockchain thoughts for the Irregulars, and also some portfolio news (including some cobalt-related) -- I bought two stocks and sold one this week and those are updated as part of my commentary on the Real Money Portfolio.  Paid members can see that by clicking here.

And in case you're a paid member but missed the note last weekend (maybe you joined up during our Gumshoe Gives Back campaign this week -- if so, thanks again!), Dr. KSS also shared a new piece about Arch Therapeutics that you can see here.
