Major sentiment-reversal signal on 12th November for Bitcoin was again proven correct – resulting in a gain of almost 40% in around a week

We track millions of social media posts and use machine learning to determine sentiment for hundreds of cryptocurrencies in real-time. Below is real-time sentiment of tweets for Bitcoin over the last ten days.  The real-time sentiment of Bitcoin suddenly made a major sentiment reversal in the evening of 12th November. As we have already posted in other such cases in the past this means a major signal for the price and indeed the price of Bitcoin has since then rallied from 5998 USD to 8179 USD for a gain of 36% in just one week. Another great BittsSignal from our real-time sentiment at just the right time. For other similar examples of how our real-time sentiment helped in recent upturns and downturns of Bitcoin and other cryptocurrencies see our BittsSignals posts. You can get access to real-time sentiment and many other advanced information about hundreds of cryptocurrencies by subscribing to our BittsAnalytics platform.

What is happening with Bitcoin Cash through charts and numbers by our digital assistant AiDA

Bitcoin Cash is really surging in the last days. So we decided to add some charts and numbers by our digital assistant AiDA. First come the prices, real-time sentiment and social media activity in the last 24 hours:

That there is great interest in Bitcoin Cash can only be seen from the social media buzz, the number of tweets mentioning Bitcoin Cash has greatly increased over the last week. 

Finally a quick overview of some numbers regarding returns, sentiment, trading volume, buzz, Bitts Rank for Bitcoin Cash:

Bitts Rank of 0.75 shows that Bitcoin Cash has indeed a very good momentum. If you would like to also have such information at you fingertips and many other tools please visit our website and subscribe to our analytics portal.

Bitcoin Cash is the big winner in the last week

Below you can find a scatter plot of over 150 main cryptocurrencies plotted against one week returns and yesterdays returns. As you can see Bitcoin Cash is really towering above almost all of the cryptocurrencies. Returns are based on EOD prices. Bitcoin Cash delivered another huge return today as well.  It is possible that the Bitcoin Cash is viewed as having less competition from Bitcoin after cancellation of Segwit2x. Bitcoin is already firmly established in the domain as storage of value. It will be interesting to watch the relative performance of Bitcoin and Bitcoin Cash in the next few weeks.

Bitcoin Cash with great increase in social media posts and reversal in sentiment

Bitcoin Cash is currently surging price. Also surging is the social media interest in Bitcoin Cash as well as its real-time sentiment that we determined with machine learning from tweets about it:

One possible reason is that after cancellation of segwit2x for bitcoin, the latter will be viewed less as a competitor in transaction space and more as a storage of value.

Remarkable outperformance of Mean CVaR based dynamic allocation between cryptocurrencies

Our BittsAnalytics platform offers our clients a multitude of strategies for generating alpha – from using real-time sentiment (for more information see e.g. blog posts about BittsSignals), social media mentions, AI analysis of clustered themes, price signals, Bitts Ranks and others. In this post we would however like to introduce you to a remarkable performance of a strategy better known from traditional finance – dynamic allocation. We use dynamic allocation between cryptocurrencies based on Mean CVaR porfolio optimisation, which better captures fat tails and is thus better suited for the volatile world of cryptocurrencies as opposed to more widely known and technically much simpler mean variance method.

To illustrate the power of dynamic allocation we intentionally chose a conservatively constructed portfolio consisting of only the “old” coins with longer histories – Bitcoin, Ethereum, Litecoin, Monero, Dash, NEM and Augur. Dynamic allocation was performed by determining optimal portfolio every five days and investing in it at close prices (UTC time). Portfolio optimisation objective for this presentation was the maximization of expected risk adjusted return (R-lambda*CVaR, lambda=0.01). Returns were historically approximated with sliding 10-day window. While the results presented here are for a certain set of parameters they are remarkably robust over the wide parameter grid and the chosen set is not even the one with the best performance. We will post results for the multidimensional grid of parameters in later post.

Let us look first at the NAV curve (period is from start of 2017 to 7th November 2017).

The Crypto Portfolio (orange line) is the NAV line of the dynamic allocation strategy. What is remarkable is that not only it outperforms the benchmark it outperforms all of its constituents (we chose Ethereum as benchmark as it is rather demanding in year 2017, we will post comparisons to other benchmarks in follow-up posts) . We have done hundreds of similar strategies in the traditional finance for various clients with portfolios consisting of ETFs, mutual funds or stocks for a wide variety of purposes including for robo advisors. In almost all such cases the outperformance of all of its members never occured. One insight from this result is that the cryptocurrencies are still sufficiently distinct from each in the temporal distribution of returns. This makes dynamic allocation based on Mean CVaR very promising indeed.

Let us look next at composition of optimal portfolio over time.

The weights were limited at maximum 60% except for Bitcoin and Ethereum which could reach 100% share. In the first half of the year Ether was several times the preferred allocation while in the last few months the optimal portfolio was dominated by Bitcoin. This is also seen from the following chart of average weights over this period of the cryptocurrencies with Ether having the highest share followed by NEM and Bitcoin.

It is also interesting to examine return contributions, see the chart below.

The highest contribution came from NEM followed by Dash and Ethereum. Profitability (return contribution divided by average time share) was also highest for Nem followed by Dash.

We conclude with performance and risk statistics of the results as well as comparison with the benchmark (Ether). Dynamic allocation strategy vastly outperformed the benchmark (alpha of over 10.000%) while achieving this with 20 percentage points lower maximum drawdown. Better risk adjusted performance is also reflected in a better Sharpe ratio.

We would also like to note that the strategy based on dynamic allocation presented is with a rather long rebalancing period of a few days. Application on smaller time scales with rebalancing period reduced from days to minutes or even less can lead to potentially even greater performance.

Finally we would like to highlight another advantage of dynamic allocation. It can effectively help with one of the biggest future problems of cryptocurrency funds – dealing with periods of severe market downturns. We will show how dynamic allocation combined with cash asset can alleviate this problem in one of our future blog posts.

Major warning signal from our real-time sentiment for Bitcoin was again proven correct

We track millions of social media posts and use machine learning to determine sentiment for hundreds of cryptocurrencies in real-time. Below is real-time sentiment of tweets for Bitcoin for the last few days. The real-time sentiment of Bitcoin suddenly turned negative yesterday and in the evening. As we have already posted in other such cases in the past this means a major warning signal for the price and indeed the price has since fallen from around 7250 USD to the current price of around 6890 USD. Another great BittsSignal. For other examples of how our real-time sentiment could help you in trading cryptocurrencies see our BittsSignals posts.

What people were writing about during yesterdays surge of Bitcoin

We are tracking millions of social media posts and generating tag clouds as well as themes of similarity for each of over 150 cryptocurrencies we are tracking. Our platform thus allows to track in real-time what people are talking about each of these cryptocurrencies and this is interesting especially in days like it was yesterday for Bitcoin. If we look first at the hourly Tagcloud about Bitcoin during the price surge it is clear what was on most people’s minds – cancellation of Segwit2x:

If we look at themes of tweets which are clustered together according to their similarity you have a similar picture from the clustered words – fork, suspended, cancelled, segwit2x, termination:
