The growth of coins has changed the way people think. Now it is not about creating them. About using them. Making a coin is not the hard part anymore.
The hard part is making sure stable coins can move easily from one system to another. Banks and other financial institutions need to know how much transactions will cost and they need things to work the way every time. They also need to know that the system will keep working even if something goes wrong. Plasma is trying to solve these problems by making sure that a lot of transactions can happen at the time and that the fees for these transactions do not change too much. Stable coins are very important, in this process. Stable coins need to be able to move across systems at scale. This is what Plasma is trying to achieve with coins.
