I paid for a VPN service in 2011 for 0.19 BTC / (~5$ USD or something back then) which is now worth over $3300 USD at today's price...to me it shows that we are not dealing with a currency, if all you can do is hold and avoid spending it in fear of "losing" money then it has no real value except selling at the right time so someone else can buy your share, hold it and eventually sell it and so forth..
