Active addresses increased for most of the major cryptoassets over 2019, a positive sign for overall crypto adoption. USDT_ETH, LINK, and XTZ saw the largest growth in 2019 while XRP, XLM, and ZEC saw decreasing activity over the course of the year with XLM decreasing by a whopping 66%. Note that the XTZ active addresses line appears thicker than other assets because XTZ has staking payouts on a regular basis, which leads to high variance in activity day-to-day. — link
