There is a reason you can only file every 7 years or so. Problem is over these 7 years many fall back into their old habits and start racking up credit card debt again and the cycle repeats. I don't remember the exact statistics but I think it is over 50% will refile for BK if they have done it once. Regardless of what you think, I have heard of people getting approved for small limit credit cards 1 day out of BK. As far as a auto or home loan, there are plenty of predatory lenders that will do high risk loans for a high enough interest rate. BK is not looked at same way as it used to be. These lenders and CC companies are glad to do the loans because they know they are safe for at least 7 years.
so it is really not a big problem. I never understood those who want to trade prop with zero money upfront, that right there is a red flag to me that says you are not confident enough in your trading ability to put your own money on the line.
