Build your Crypto portfolio following the marketcap using Coincube

One of the most difficult things about investing in and trading crypto currencies, is the enormous choice in coins and tokens. Which ones should you hold and how much? Like most people, I guess, I have a couple accounts on exchanges like Gdax, Bitstamp, Poloniex, Bittrex and  HitBTC. So how much do you hold on each exchange? And what if you have some holdings on a wallet outside of an exchange?

Introducing Coincube

I have been looking for a way to manage all these holdings and accounts. I used spreadsheets and tools like blockfolio. I did ok, but it was a lot of work keeping track and to keep adjusting my portfolio as markets change. A few month back I came across  Coincube. Coincube is a free service, that let's you connect your exchange accounts and wallet, so you can manage them as one portfolio.
Coincube let's you:
  • connect trading accounts for automatic trading
  • set your portfolio to follow the marketcap of the top 5, 10, 20, 30 or 50 coins
  • set an ethereum based portfolio
  • set your own portfolio
  • view performance over time
  • re-balance your portfolio
Here is a performance chart:

Set your desired portfolio

The Coincube generator page let's you generate your own portfolio or you can choose from an Ethereum based portfolio or one of the market cap following portfolios. In case of the later you can choose from the top 5, 10, 20, 30, all to the top 50 coins in the market cap. After you have selected your portfolio you can set to what extend it should follow the market cap of be equally weighted. The more you choose equally weighted the more "aggressive" your portfolio will be. If you wish you can also set a percentage of fiat between zero and a hundred percent to re-balance the complete portfolio against fiat currency. This should make the portfolio less volatile, but potentially also less profitable.

And here is an image of a portfolio:

Supported exchanges

The following exchanges are currently supported:
  • Bitfinex
  • Gdax
  • Bitstamp
  • Gemini
  • Kraken
  • Poloniex
  • Bittrex
  • HitBTC

Distribution of funds

Once you have connected your exchanges via their respective apis and set up the wallet addresses to follow, you will have an overview of what percentage of your funds is held where. You can then start to redistribute your funds. It is important to not keep your funds at just one exchange, because if something happens to that exchange all your funds might be lost. Therefore I suggest to keep funds distributed over at least 3 exchanges and keep funds you want to HODL in wallets that you control yourself. I use Gdax and Bitstamp as my main exchanges. They offer the main cryptos against fiat. A smaller amount of my funds I keep at Bittrex and HitBTC. And I HODL my cryptos on my Ledger Nano S. In below video I show you my Ledger Nano S. I have a accompanying blogpost here:

Still in beta

Coincube is still in beta and I have noticed the occasional bug / hick up. But hey it is free! Still, a few weeks ago coincube disabled the continues re-balancing feature as it was causing some users issues with wrong trades. I think this mostly had to do with the in flux of new users into the exchanges that might have slowed down, or temporarily brought down many of the exchange apis that Coincube uses to do the re-balancing. Automated re-balancing is now done weekly. So if you want to do more frequent re-balancing, then your should do this by hand. I do this by turning the automated trading feature of and on or by re-indexing the portfolio.
