Why sell alts for BTC when they're already priced in BTC? All else being equal any gains you make on BTC are already included.
If Bitcoin went from $250 to $10,000 tomorrow, would you keep your alts or sell all of them for BTC.
i'm sure 99% will sell alts -> btc -> fiat and cash out to never look back. simply because most was dragged in crypto for the "get rich quick" dream.
and based on this simple fact (cashing out and gtfo), it's impossible that bitcoin raise that much in value.
simply by suggesting a $250 to $10k (lol) sustains the downward spiral mentality.
keep dreaming
