174m is nothing in terms of the crypto market and you cannot even be sure that this money entered the market
It's a big thing actually. It's buying a stable coin out of these exchanges who are offering it available, and I think it's a safer way of entering the market because it wont print unusual green candles. Btw, these stable coins are also cryptocurrencies but only is backed by dollars to maintain it's stability and safety.
But it still could be that it was just funds being redistributed from one stable coin to another. Even if it is new money I stand by my point that it is not hugely relevant. While I understand marketcap isn't a true reflection of the money in a market, it still gives a vague idea. 174m in to a marketcap of over 100bn is a drop in the ocean.
