It's a respectable gain. But with these kinds of risks we're taking a heavier gain should be expected. The old adage, "High risk, high reward" most certainly applies to pinks. If you are investing here you really should expect more or else it will catch up with you. More pinks fail then succeed and you need to compensate for it somehow. 50-100% would be a better expectation/target; opinions will vary I'm sure.
I wasn't going to comment on that but it was brought up.
