Why invest with coindex?

Crypto is huge: There are more than 5,000 crypto assets and new ones are coming up every single day. Trying to keep up with that is a task that requires lots of effort from a single person. And questions like "Should I buy Bitcoin?" "What about Ethereum or Ripple?" are difficult to answer. 

That's why at coindex, you can choose an index-based portfolio. Sounds complicated, but it actually makes life easy. It works like a basket, in which the most important cryptos are automatically added to your holdings. A computer program selects the cryptos and balances them so that they mirror the development of the crypto market. The result? You don't have to worry about selecting individual cryptos any more (just like an ETF).

And if something changes in the market? Well, computers never sleep. 

That's why your computer algorithm for the index-based portfolio quickly adjusts to the market situation. Automatically. That way, our index-based portfolio currently manages to cover about 85% of the development of the entire crypto market.

You'll have access to one of the widest ranges of crypto offerings in Germany with 20 cryptos currently, and more to come soon. And at coindex you will always own your cryptos directly and we will take care that they are savely stored. 

Can I cancel at any time?

Sure, you can cancel at any time.

May I sell my crypto any time?

Yes, this is possible at any time. Just log in to your account and choose which assets you want to sell.

When you sell, you will be charged a trading fee of 0.5%. So, selling cryptos worth 100 €, you will be paying a 0.50 € fee.

How secure is coindex?

Sutorbank ensures that your money is secure and von der Heydt Bank safeguards your crypto assets. All of this is supervised by the German financial supervisory authority.
