I bought 2 for cold storage @$230, and 1 for my nephew for Christmas. I figure it'll pay for his college in 10 years since he's only 7. I also bought us 25LTC to hedge the bet... Can't hurt, right? The BTC I spend, I buy as needed at market rate...
It is a very good idea to buy back the bitcoin you spend. You are circulating the bitcoin, making it very valuable
