I'll start with the exchange rates. Without a doubt, NiceChange doesn't always have the best rate 100% of the time and not for all currencies. You have to catch the right moment or accept small losses to accumulate discounts and not depend on insignificant differences in fees between various exchangers. Nevertheless, the rates are generally good, especially for popular currencies. I usually check the rates on BestChange before each exchange, and NiceChange often ranks among the top. Now about the ease of use. The exchange process is no different from other services; the principle is the same. However, here all available directions are grouped together, rather than just laid out in a mess like many others. Three groups have been created: cryptocurrency, banks, and electronic payment systems. As for the directions, there are quite a few: about 20 different tokens and about the same number of banks, but wallets are a bit unfortunate. WebMoney, PayPal, and similar services are absent. Nevertheless, for cryptocurrency conversion, this exchanger is ideal, as it works with the most popular coins. The exchange speed is high; usually, the money arrives within a few minutes. However, with BTC, the situation can vary, as there have been recent issues with the network, causing transfers to be delayed. But that is beyond the exchanger's control.
