Bitcoin is still managing to take shape out of endless emptiness.

Ethereum has gotten unstable.
It’s still not bad—if there’s profit, it’s fine.
Choose the right direction; it far surpasses blind effort. Most people’s trial-and-error costs are already limited, and they simply can’t make it to the top—they often burn through their energy before they even reach the halfway point. What we need to do right now is to rely on limited trial-and-error costs to maximize returns in the shortest possible time; only by knowing how to go with the flow can you achieve an unbreakable strength.
