Opis:
Subject and purpose of work: The purpose of this work was to compare selected portfolio strategies in terms of return rates in order to answer the question whether the method of determining the weights of the portfolio and reduction of the number of portfolio elements characterized by strong positive correlation of rates of return have an impact on its profitability. Materials and methods: The analysis used publicly available data, selected portfolio methods and hierarchical clustering. Both short- and long-term investment strategies were examined. Results: None of analyzed strategies allows to achieve higher rates of return in any given (arbitrarily selected) period than other analyzed strategies. Portfolios with a reduced number of elements in most cases did make it possible to achieve a higher rate of return than the benchmark portfolios consisting of 15 cyptocurrencies. Conclusions: While making investment decisions, one should bear in mind that the realized rate of return may significantly differ from the expected rate of return of the portfolio, which is only a forecast.

PROMETHEE II
Opis:
Subject and purpose of work: The aim of this work is to present the application possibilities of PROMETHEE II method used to create a ranking of cryptocurrency exchanges as well as comparing the results of multi-criteria and multi-dimensional analysis. A simulation method for determining the weights of criteria is proposed, which maximizes the similarity of the final ranking to the other ones. Materials and methods: PROMETHEE II method and taxonomic measure were used to create rankings of exchanges. Hierarchical clustering combined with the k-means algorithm was used to identify groups of exchanges with a similar level of the values of net flows. Publicly available data published on the Internet were analysed. Results: There was a high consistency in the ordering of exchanges when a multi-criteria and a multi-dimensional approach were used. Four groups of exchanges with a similar level of the values of net flows were identified. Exchanges in group one were characterized by the highest average net flows. Conclusions: The multi-criteria approach can be used as an alternative to the multi-dimensional assessment of cryptocurrency exchanges. The proposed simulation method for determining the weights of criteria can be helpful in case the researcher has no information about the importance of the criteria.
