That's interesting, I do not think a gambler would take such a drastic step
Secondly, I myself have thought that if I had not traded bitcoins for small marginal profits and instead holded on to them then I would have made a good decent profit now. I am not aware of any fixed duration bitcoin storing schemes, like banks do, but still if they exist they are a couple of risks involved.
1. You asked them to store your bitcoins for 1 year, but there is no guarantee, site turns scam, coins gone.
2. You asked them to store bitcoins for 1year, price is stable for the first 6 months and then the price starts to collapse, you cannot do anything, you have to wait for 6 months. And in this situation your storing venture would end up in loss.
Why go through all this hassle, just have a bit of self-control
