Even if Steam's future seemed very bright after launching, but the question of starting a steady decline immediately after the price is that if steamitre is a great platform, then how does the price fall constantly?
An explanation that comes to me is that the change in value reflects the supply and demand of a specific currency when the price increases - there are more buyers than vendors, when it goes down - if more sellers are buyers then Before the live steam, the platform was in beta because there were no sellers in all, people could only buy steam but could not cash on it, hence the logo Bought into the dream of "Steam", an investment of money and time to create great content. These people were paying for their content but they could not cash on the money.
Following a full steam operation, a multitude of Steam users cashed Steam Dollar in steam, and then steam the cash out of Bicicone or their local currency. This is the reason that in my opinion prices are falling after the launch. People do not have real use for steam because it is not accepted anywhere, so when they get some steam in their hands, they do business quickly. Combine the fact that apart from speculators there is no real incentive to invest in steam and you get a huge amount that runs down the price.
One of the main reasons is that steam did not completely collapse after launch in my opinion, due to the fact that all your steam can not be traded at once. Steam power has a limit of up to 104 weeks, unless you can fully cash it, so it closed the price expense and made it a bit more manageable.
