Runes are new meme coins or fungible tokens created on the Bitcoin network, similar to how there are meme coins on other blockchains like Ethereum. Lark believes runes represent a potential 100x investment opportunity within the Bitcoin ecosystem while it’s still early.

Some key points from Lark:

🪙 Runes are the next generation of fungible tokens on Bitcoin, built to be simpler and more efficient than previous iterations like ordinals and BRC-20 tokens.

💰️ The combined market cap of all runes was still very low (under $1 billion) when Lark made the video, leaving room for growth.

💪 Being built on Bitcoin, the largest blockchain, gives runes an advantage over meme coins on other chains.

🔗 Lark draws parallels to ordinals and BRC-20s, which had slumps early on before delivering big gains to early investors who held through the dips.

📜 Notable rune projects mentioned include PUPS, Rune Coin LOBO among others.

While acknowledging risks like trading friction and possibilities of fading away, Lark presents runes as an intriguing early investment opportunity in the trendy meme coin space, but within the Bitcoin ecosystem.
