I think he means it is going to $28K, not was. Did he say it was going there within a few days? Price was still at $23K at the time of your posting because it was consolidating at support. While the OP hasn't revealed a chart to back up their claims, then it's what a lot of people are seeing right now: no resistance until $28K to $30K levels if $25K is broken to the upside. This doesn't mean it'll get there in a straight line, probably continuing the higher highs and higher lows trajectory price has already followed so far from around $20K. The OP is just pointing out how many remain bearish while price action, short to mid-term has turned bullish.

For example based on moving averages alone (which are very lagging indicators), price on the 4hr is fully bullish. On the daily chart it's mid-term bullish (above both short and mid-term MAs). On the weekly chart 200 WMA at $23K is being confirmed as support for the third consecutive week now, despite many expecting (wrongly) that price would get rejected there as it fell below for a few weeks. I'm not even saying that price will definitely get to $28K, simply that it seems more likely than further downside right now, as there is a big volume gap between $24K and $28K while $20K to $22K has become srtrong support.
