I'm sure they are trying to lure people who cannot repay, or keep up with monthly payments into making a poor choice. My situation is quite different. I feel like I'm cheating them at their game.
IMO that's a fool's game.
I’ve done similar things, though not quite the doubling in stocks! Way to go. There are some risky buys out there right now, but the upside potential is also enormous. Good luck to you!
I’d only do that if I had more than enough cash to cover that and then some.
