mond.reise currently supports connecting to three derivatives exchanges: BitMEX, FTX and Deribit. More to come. This Article intends to help you with your decision.

BitMEX

Founded in 2014, BitMEX is the oldest player in the derivatives markets. It „invented“ the perpetual swap contracts, which most other exchanges used as reference for their own products. The CEO, Arthur Hayes, worked for Deutsche Bank before he got fired. BitMEX has a controversial reputation, because it has been unregulated and encoutered many law suits with U.S. authorities.

Technically, it has high security standards and a mature trading engine.

Pros:

• -0.01% maker fees (you get paid for every trade)
• Shared margin (Bitcoin)

Cons

• Bitcoin-only deposits

FTX

Pros:

• EUR, USD deposits
• Shared margin (USD and Bitcoin)

Cons:

• High fees (so less expected return)

Deribit

Pros:

• 0% maker fees
• Better reputation than Bitmex

Cons

• Seperated margin for Bitcoin and Ethereum contracts.
• Currently mond.reise only supports Bitcoin trading on Deribit

Conclusion

Chose BitMEX for highest expected returns. FTX is an all-in-one solution with bank transfers. Deribit is a safe alternative with zero fees.

Open yoroi, then open developer tools. In the JS console paste the following code:

Export

connection.onsuccess = e => {

Import

var connection = indexedDB.open('yoroi-schema', 16) // change the name and version as needed
connection.onsuccess = e => {
  var database = e.target.result
clearDatabase(database)
  importFromJson(database, json).then(console.log).catch(console.error)
