So, my thoughts....
I don't know that there's a right or wrong answer to this. This past week, I've been flipping Mixels Series 1 sets for 2x RRP. Some of these sets I've been holding onto since June. Others, I held onto for less than 24 hours.
I'm approaching a similar cost on Mixels, as I would on one SSD. And that's part of what got me thinking about this topic. In three months time, I've doubled my money, for the same cost as owning an SSD. (Yes, I've been able to pick up both an SSD and Series 1 Mixels within the last three weeks). Short term, the SSD isn't at 2x RRP. And, if I'd be holding onto an SSD for longer than a few months, and I was worried about cash flow, then maybe that would be a problem. (Personally, the SSD was a long hold item for me).
For me, I'm willing to hold onto the SSD until it gets well over 2x RRP. I don't believe Mixels Series 1 is going much higher than it is now. But who knows? I could be wrong about that.
It was just an interesting thought/reflection that I've been able to quickly flip (which is not something I normally do, either).
