Wise words.
I have 3 Ethereum mining rigs (2x6 GPU and 1 5xGPU) being built at the moment and I started buying ETH recently when it was at $53, it went up to $83 and I thought it would continue so ordered all the components for 3 rigs. The parts have only just arrived and the price has gone way up and now on it's way back down.
However - I was happy enough to buy the hardware when the price was at $53 so - the current price of over $150 still looks very appealing and I think it'll go back up so I'm not bothered about the price changes.
Luckily while my hardware is busy mining ETH I will be busy interacting in the STEEM community :)
Cool!
