Exchanges are the beating heart of cryptocurrency trading, and already have a daily trading volume of billions of dollars. For retail crypto traders, these exchanges are the most common (and often the only) marketplace in which they can trade coins in a convenient and safe manner. Following our guidebook for choosing the right exchange, we will start reviewing the largest crypto exchanges, starting from Bitfinex.
Bitfinex, which was founded in 2012, is operated by iFinex Inc., which is located in Hong Kong. The exchange has more than 60 trading pairs, and is the world’s largest exchange by trading volume.
Bitfinex is an exchange with a wide range of trading capabilities and trading pairs, but its somewhat complicated user interface may make it difficult to use for those new to crypto trading. Bitfinex’s history of large-scale hacks certainly raises concern about the exchange’s security, but the exchange’s response to each of these incidences has managed to keep its reputation afloat (or at least, somewhat afloat).
- ‘Chain Split Tokens’, which are coins that allow users to trade speculatively on the future success of coins forked from the Bitcoin blockchain.
- Private users making trades worth over $100,000 can make use of Bitfinex’s OTC trading service, which matches major deals.
- Margin trading with a maximum of a 3.3x leverage. Users who allow their BTC to be lended for margin trading earn interest on their tokens. However, leaving tokens on the exchange may make them vulnerable to hacking; margin lending requires users to leave their tokens on the exchange throughout the duration of the loan.
- A variety of order types, including limit orders, market orders, one cancels other (OCO), stop orders, trailing stop orders, post only orders, hidden orders, fill or kill orders, iceber orders, and Time Weighted Average Price (TWAP) orders.
Bitfinex has dominated the BTC market in terms of trading volume over the last six months, as shown in this graph from bitcoinity.org:
Privacy and Security
It is possible to sign up for an account on Bitfinex using nothing but an email address–such an account can be used solely for crypto trading. However, identity verification is required for users who wish to deposit or withdraw fiat currency on the exchange. Identity verification is also required to expedite the withdrawal process. There is no buying limit on Bitfinex.
To make accounts more secure, users can enable two-factor authentication through Google authenticator, Twilio, or a U2F Security Key.
Bitfinex does not offer very much information about how security on the exchange works for “security and proprietary reasons.” However, Bitfinex does say that the vast majority of the cryptocurrency on the platform is stored offline in cold wallets.
Bitfinex’s support center (bitfinex.com/support) allows users to “open a ticket” to request help from the staff, although some users have reported via Reddit that several weeks passed before they received answers to help tickets they submitted.

Users can also submit questions about deposits and withdrawals, and receive guidance on recovering access to blocked accounts.
- Taker Fee of maximum 0.2% (users trading more than $30 million a month have their fees reduced to 0.1%); Maker Fee of 0.1%.
- Withdrawal fees vary by cryptocurrency:
- Margin providers are charged 15% of the fees that they receive; if the fees are provided through a hidden offer, the charge increases to 18%.
- Bitfinex supports bank wire transfers with a minimum $20 fee.
- The Bitfinex interface is rather complicated and takes time to understand. If you are new to trading cryptocurrency, be sure that you know exactly what you are doing–mistakes can be costly and are often irreversible.
- For more experienced traders, Bitfinex is an attractive option for a few reasons. In addition to having high liquidity in BTC and ETH, Bitfinex’s support of margin funding and multiple types of orders make it an exchange with a diverse set of capabilities.
Hacks and scandals
Bitfinex’s success has not gone without its fair share of hacks and scandals.
The first took place in May 2015, when 1500 BTC tokens were stolen.
In April 2016, north of 120,000 BTC tokens (worth approximately $72 million at the time) were stolen from the exchange. However, Bitfinex socialized the losses, spreading them evenly across all of its users. Eventually, Bitfinex compensated users for their losses.
Bitfinex suffered more trouble in April of 2017 when the exchange’s bank, Wells Fargo, put a hold on the exchange’s accounts. Although everything went back to normal after the hold was released several weeks later, customers complained of distorted pricing during the freeze. The ordeal resulted in the decision to remove the support of fiat currencies from Bitfinex, although fiat returned to the exchange in late November.
Most recently, $31 million in Tether dollars were stolen from Bitfinex in November of 2017. The close connection between Bitfinex and the Tether company has raised more than a few eyebrows–the two companies are essentially run by the same two men, Phil Potter and Giancarlo Devasini.
I am officially seeking donations to defend myself against Bitfinex’s frivolous lawsuit, rather than showing their numbers they seek to silence me.
I appreciate all the support you all have given me.
