What? Which altcoin do you think has better tech, better security, better development, or better functionality than bitcoin? I can count on one hand the number of altcoins which aren't a complete waste of time and actually have some real merit to them, and still none of them are better than bitcoin. The majority of top ranking coins are either useless or outright scams. Which altcoins has the "best blockchain" in your opinion?

Using market cap as a marker for how good a coin is is pointless. I could create a token in under 30 minutes, print 100 billion of them, and then sell a single one to my friend for $5. My token now has a market cap of $500 billion, has overtaken bitcoin, and is the number 1 cryptocurrency in the world. That doesn't make it useful, good, or even not a scam.
