Just finished reading the Coindesk article. Truly remarkable what that person did, as also pointed out in the article itself "Not bad for a few minutes of work. But just imagine how long it took for someone to figure this out."

And I think the second sentence is the key, it seems that this person was the first that did it to that extend with this setup. Truly something fantastically planed and executed, certainly with the necessary knowledge and financial background in case something goes wrong. Also, if you are a small investor and just trade around 10-20K or as most newbies do even lower then you aren´t even able to put of such a stunt financially as well as mentally. My experience is, if you aren´t used to big number they scare you and having 45K and taking a 405K loan is something not everybody would dare. Looking forward if they close that gap or if more people jumpt that bandwagon
