AVAX has been on a tear lately, rising more than 40% in the last three days. This impressive performance has made it one of the top gainers of the week. There are a few factors that may be contributing to AVAX's recent surge. First, the overall cryptocurrency market has been on an upward trend in recent weeks. This has helped to lift all boats, including AVAX. Second, AVAX has been benefiting from positive news and developments. For example, the Avalanche Foundation recently announced a $200 million ecosystem fund to support the growth of the Avalanche ecosystem. This is a significant investment that is likely to attract more developers and users to the Avalanche platform.
