The signal/noise ratio on that subreddit was unusablely low start at least ~2017. /r/btc is marginally better, but most of the popular cryptocurrency subreddits are very low quality.
/r/bitcoin is a heavily monitored and censored subreddit. Anything not in line with message is deleted, anyone who tried regularly is banned or shadow banned. It is basically /r/thedonald for cryptocurrency. Even here if you post something negative about it here you can see your votes go down in clusters (while possibly going up in between).
