What if ajareselde is right and anyone who was going to buy bitcoin has already bought? It's not like it's a secret anymore. And there's a huge group of people who are simply not capable of understanding or being able to use bitcoin. It's not easy or safe for the average person.
We've already hit China but maybe there's still more market there in China to reach.
The big one that we haven't hit yet is Wall St. so hopefully this ETF gets some action going.
