Someone asked: Why is it so difficult for public blockchains to be fast, cheap, and secure at the same time?
I usually answer this way: Different public blockchains use different consensus mechanisms and make different design trade-offs, so their block times, confirmation speeds, and fees also vary. The more dispersed the validator nodes are, the more messages they need to exchange to reach consensus, making it harder to improve performance. That’s why these three goals constrain one another.

Make your own decisions when buying or selling—don’t just follow the crowd.
