This could be a common manipulation to make market participants believe that a bull market is now beginning and thus begin to buy. Don't forget, the market is manipulative and often the big players create purposely needed conditions, which many participants are waiting for. Although this does not negate the possibility that it could be the beginning of a real market reversal, but I would not rush too much and wait for more signals confirming increased demand for cryptocurrencies and new players coming to the market.
