For work, the most important resource is proxies. Their main application is in projects. In my case, the best option is the ability to open proxy ports, and the proxies themselves automatically rotate after each request. There's also the option to get proxies via a link, which allows you to obtain a large number of IP addresses at once. The rates are calculated solely based on the traffic used. I buy addresses in large quantities, and even with such volumes, the rate at Ake remains the most convenient, as on other platforms, ports often run out, traffic issues arise, or other problems occur. They do not round traffic to the nearest kilobyte, which is also an advantage for optimizers like me.
