BTC dropped from $ 61,500 to $ 50,000 today, rising again to $ 55,500. The rapid decline came after rumors surfaced that the US treasury blamed various financial institutions trying to launder money using cryptocurrency. This news has not yet been confirmed. Despite this, investors were affected by the news, and high sales were made.
In fact, you should not be affected by such news, otherwise you will sell at a loss. After the sudden drop, BTC started to rise again and it looks like this uptrend will continue. If nothing negative happens, I think BTC will return to the same levels in the next few days.
