For this second I see the dominance of Bitcoin trading is around 39% on the Coinmarketcap website.
I admit that I don't really understand if the dominance of Bitcoin trading goes up or down because I'm also sure that the higher the dominance, the Bitcoin goes up.
But maybe my judgment is wrong because I don't really understand the dominance of Bitcoin trading size, maybe others can also reply to my message and can discuss more fully in this thread.
