Only invest what you can afford to lose.
If you are borrowing to do it, you can't afford to lose. (As much as I joked about taking a $10,000 0% line of credit on one of my credit card offers if the price went down to the $100s, I seriously wouldn't do it. I don't borrow to invest.)
That said, I DID borrow against my 401k to invest, but I consider that OK for the following reasons:
1. I have it covered by my outstanding vacation should I lose my job
2. I am paying interest to myself, not somebody else, so it's not a loan in the traditional sense. In fact, I make MORE money every month.
3. I want to invest a percentage of my "retirement" in bitcoin (retirement in quotes because I plan to retire this year but I can't touch that money for decades) but there is simply no other way to do it
Please don't borrow to invest. Bitcoin could still easily go to zero.
Thanks for that.
I know we probably don't see all things completely eye to eye, but it's good to see that one of the big optimists in here (which I'd say you are) is giving fair advice to the newcomers.
The rule really is: "don't invest what you can't afford to lose".
What exactly you "can afford to lose" depends on your income, age, family situation, etc. But a large loan that could ruin you if Bitcoin price goes drastically down, or just stagnates for years, is pretty much never something you can afford.
