First time poster (long time lurker)...
As my user name suggests, I am about to make, by far, the largest bet of my life and will be buying 1,000 shares of Tesla once the funds clear in about a week or so. I will be using a good amount of borrowed money to make the purchase (which includes some margin from my broker as well).
Fortunately, I have a pretty good and steady job that would allow me to pay back any loses within 4-5 years or so if things go south (I am a CPA as well so even if I lose my job I should be able to fine another one fairly quickly in my market). The way I see it, I am borrowing from my future to buy Tesla at this level today, as opposed to buying the same number of shares over the next 4-5 years.
I would never recommend this to anyone and am still having second thoughts myself but on my death bed I will look back at this and say I am glad that I did it (whether it works out for me or not).
Good luck to all but especially Tesla!
