I used an aggregator for one of my projects. I needed a service for accepting cryptocurrency payments, and I decided to test it. It supported not only popular coins (BTC, ETH, LTC, and others) but also lesser-known altcoins. At that time, there were 16 cryptocurrencies available. Additionally, it was possible to work with fiat currencies (rubles and dollars) through electronic wallets like Payeer, AdvCash, and others. The fees were generally acceptable; I paid 2-4% for withdrawals depending on the currency. Everything functioned smoothly, payments were received, and I could withdraw my money. Overall, PayKassa does its job 100%. The aggregator also offers a Russian version, which makes it convenient to use. All the necessary information for settings is provided, so there's no need to bother support with a lot of questions. The module simply integrates and works correctly.
