If this rally takes us to 10K, then the Bitcoin market cap will be around $180 billion.
When was the last time that you checked the market?or are you joking?bitcoin price now sits at $8,000 and the capitalization is $240 billion already so what more if this reached $10,000?
He is correct and your calculations are wrong.
$240 billion is the combined market capitalization for all the cryptos (BTC + alts). In case the Bitcoin exchange rate climbs to $10,000 per coin, then the Bitcoin market cap will be $180 billion ($10,000 x 18 million coins).
But I am not sure whether the Bitcoin dominance will remain unchanged. The alts are making a big comeback. XRP is up by +26% today.
