Rather than obsessively checking the price and seeing if my coins have increased in value all the while kicking myself about not getting out at the peak (a.k.a HODLing), I've hit upon a new method for growing the bitcoin ecosystem and thus hopefully the value:

I bought some bitcoin (from an ATM in Manchester, UK) and have spent them on a new Raspberry pi, some beers and a few DVD's. As the value has increased, I got the stuff I wanted at a reduced price - double win 

I believe in the future promise of bitcoin as a payment system but it's not going to grow unless it's used - stop trying to get rich and just use them!
