It's a way to get rich but for those that think you can get rich quick from it, they are sadly mistaken. If you know what you are doing and you can buy and invest or sell on at the right times then you are able to become rich from it but it will be a slow process.
If you think you are smarter than anyone else, therefore buys bitcoins, and the less smart does not, it is a
painstakingly slow get rich quick scheme.
If you on the other hand think you are medium smart, just quicker in action, and therefore buys bitcoins, the others will buy just afterwards,
it is a get rich quick scheme.
If you are medium, and slow to act, or if you are just plain stupid, it is a
get rich not so much scheme.
Obviously, as you can compute from this post, I am in the first group.
