Stop over thinking everything, a lot of people are using correction when there is a downside after a huge pump.
What is the problem with this? It is like those people who say HODL instead of hold.
Recently I've been seeing the word "correction" a lot on the forum. It's being used as an explanation for BTC's recent drop in price.
Anyway, NASDAQ has different terms for everything, and you can not compare cryptocurrencies with the nasdaq, since most of the instruments in there are stocks.
but yes, in terms, corrections, with downsides are almost the same.
