美企Skydio挑战大疆主导地位
美国无人机制造商Skydio向乌克兰交付新型X10D无人机，具备抗电子干扰能力。美国计划年底前禁止大疆等中国无人机进入市场，Skydio抓住机遇，已向650个政府机构供货。
但中国反制导致Skydio电池供应中断。该公司虽加速本土生产，总产量仅4.5万台，远低于大疆每周数万台的产量。美国基层执法部门则抱怨Skydio价格过高，单台售价达1.2万美元。
五角大楼数据显示，按目前损耗率，美军无人机库存仅够支撑5天战斗。Skydio正研发"机库基站"系统，实现911报警后90秒内自动出勤。

That said, PayPal has announced that it will enable cryptocurrency as a funding source for purchases this year, financing purchases by automatically converting crypto holdings to fiat currency for users. “They have 346 million users and they’re connected to 26 million merchants,” says Spencer Montgomery, founder of Uinta Crypto Consulting. “It’s huge.”
