People who say that Bitcoin can reach $1 million per coin at some poin in the future are not being realistic. They keep fooling themselfs. I think anything between $1000-$5000 is surely possible. Especially when Bitcoin is getting used as an investment tool by institutional investors. These guys have the money to move Bitcoin beyond what we think is possible. Without them we'll probably keep sitting below $5000 for ever. We only need Bitcoin to gain more popularity among average joe people as being a currency and an investment tool. The rest will go automatically.
