Binance also offers a generous referral program that rewards both referrers and referees with discounts on trading fees and additional perks.
2. Bybit
Bybit specializes in derivatives trading, specifically cryptocurrency futures contracts, which appeals to traders interested in leveraged trading. Bybit's referral program is competitive and rewards both the referrer and referee with bonuses like percentage discounts on trading fees or additional trading funds.
3. Crypto.com
Crypto.com stands out for its comprehensive platform that encompasses various services, such as cryptocurrency trading, a mobile wallet, and a Visa card for spending cryptocurrencies. Their referral program is equally attractive, offering referral bonuses that include cashback rewards and commission percentages based on the referred user's activity.
4. MEXC
MEXC grabs the attention of users searching for promising projects in emerging cryptocurrencies. MEXC has gained recognition for its early listing of such projects, providing opportunities for those seeking potential investments.
