I recently came across an interesting interview where Litecoin creator Charlie Lee openly expressed regret about creating Litecoin. He said if he could go back in time, he would say: just buy Bitcoin, don't start a business, don't touch other coins. It sounds harsh, but this is precisely the truth that the entire industry has been forced to admit during multiple bull markets.

Think about these past ten years—does it resemble a large-scale laboratory experiment? Countless people rushing into startups, building ecosystems, raising funds, and repeatedly trying and failing. In the end, the market has answered one question with concrete actions—Bitcoin is the entity that doesn't need to be proven.

This isn't about negating other cryptocurrencies, but rather the industry's own rules of the game determine the outcome. The market naturally favors rewards for faith and consensus, not for real value creation. You can write protocols, develop applications, tell stories, but as long as there isn't a genuine demand, the final outcome is unavoidable—being priced in, cashing out, and capital flowing back into Bitcoin. This cycle neither produces new value nor attracts new users. Under extreme zero-sum competition, trust eventually collapses.

Someone who has personally helped shape a top ten market cap cryptocurrency now says, "Only buy BTC, don't start a business"—this isn't an industry illness; it's a rational judgment based on understanding the structure. If early crypto was about the adventure of possibilities, now it's about filtering for the endgame.

From another perspective, over these ten-plus years, all chains, all projects, and all attempts may be doing one thing: continuously channeling traffic to Bitcoin through their practices. Bitcoin is the locomotive, and those altcoins are the engines driving this train forward.
