If you are able to locate the prices near the top, then yes it would make sense as you would be selling it higher than what you bought it for. The problem would be that you could be selling too late after the correction has already ended(at a low price) or missing a strong bull run. Also this will work if you trust that usdt will always equal to 1$, which might not be the case: https://www.reddit.com/r/btc/comments/6xpddt/as_20m_more_tether_are_issued_today_i_think_its/
