It offers users almost 600 trading pairs including fiat for conducting transactions with a variety of popular crypto assets. In addition to standard exchange analysis, Binance offers tools for margin and futures trading. Its daily trading volume is around $11 billion.

Users can increase the withdrawal limit to 100 BTC daily after passing the next stage of verification by providing passport scans and a sample signature, or legal information if trading is conducted on behalf of a company. The third level is personal and requires contact with the support service.

Binance attracts traders with low trading commissions, which are 0.1% - makers and takers included equally. Marker discounts of up to 0.015% and 0.03% for takers are provided for large traders. But such generosity depends on monthly trade volumes in BTC.

Binance provides extremely fast order closing and high liquidity as significant advantages. A relative disadvantage is the lack of support for classic currencies, but the platform is an excellent trading channel for beginners and advanced users, as no commissions are charged for depositing funds.

A world-class system of security layers and a rather generous program of user rewards are also granted to users for bug hunts and reports of system vulnerabilities.

Overall, Binance is highly recommended as a go-to platform for novice and seasoned traders who seek and value convenience and functionality in the interface cluster along with low commissions and a good selection of listed assets offered for trade.
