DeFi Technologies, a Canadian fintech firm, has seen a significant 25% increase in its stock price following major Q3 profits. The surge is attributed to the growth of its European subsidiary, Valour, which has been bolstered by funds for Solana, Cardano, and Near. Additionally, DeFi Technologies has doubled its Bitcoin treasury holdings and added Solana and Core to its balance sheet for the first time. The firm, trading under the ticker $DEFTF, has also added more BTC and SOL to their treasury.
