recommend Bitcoin Exchange

What is Bitmex?
BitMEX is an international cryptocurrency exchange that was launched in 2014 by HDR Global Trading Ltd. (Arthur Hayes, Samuel Reed & Ben Delo). This particular platform is cryptocurrency only, meaning that deposits and withdrawals via fiat wire transfers are not allowed – i.e. Bitcoin in-Bitcoin out only.

BitMEX offers margin trading, with leverage up to 100x on Bitcoin on the spot and futures markets. Leverage on altcoins varies and for now Bitcoin is the only cryptocurrency that offers the full 100x, with Ethereum offering up to 50x and Litecoin up to 33.3x (It is important to exercise caution with respect to current market volatility).

Advantages of Bitmex

1.Up to x100 leverage.

2.Liquidity of swaps and futures — the trading volume of the XBT/USD pair on the Bitmex exchange is the first in the world.

3.Very convenient and functional interface, understandable to those who are familiar with trading.

4.You can trade futures absolutely anonymous, which is a huge advantage for those who don’t want to leave their personal data on the exchange for confirmation. To verify your account, you only need to confirm your email address. After passing through a simple and quick verification process, you will have access to trading without restrictions.

5.No hot wallets, bitcoin withdrawals can be paid out two times a day after manual verification.

6.Funds are deposited to or withdrawn from BitMEX only in bitcoin. Bitcoin is also used to secure any contracts on the platform, be it BCH/XBT, LTC/XBT or any other trading pair.

7.For some people, Trollbox is an added advantage, but I would say that for me, chat distracts more than any valuable information it I could get from it.

8.Good customer service.
