IntroductIon Dear Readers and Authors, It is with great satisfaction we present to you the fourth issue of 2018 of the sci- entific quarterly Copernican Journal of Finance & Accounting. I would like to give thanks to the Authors, Reviewers, Members of the Scien- tific Council and the Editorial Team for your special contribution to the devel- opment of the journal. Copernican Journal of Finance & Accounting as a place for the exchange of academic thought creates an opportunity for the presentation and discussion of the current and important problems of economy and finance. Scientists from various academic centres from Poland and abroad have prepared the articles that make up this publication. In the current issue you can read articles about the wealth management market in China, the social background of Brexit, and about the inf luence of crypto currency on the economy of Georgia. You will be able to find articles about promoting the transparency of the economic process by accounting, and about the importance of financial reporting for individual investors. One of the articles is devoted to the legal and economic approach of the financial stability of local government units. The subject of another arti- cle concerns the measurement of profitability of corporate social responsibil- ity activities. In the journal, an article relating to the role and consequences of banks using sales techniques such as cross-selling and up-selling is also pre- sented. I encourage you to read and publish in the Copernican Journal of Finance & Accounting. I hope that this publication will be appreciated. Yours sincerely, Executive Editor, Dorota Krupa, Ph.D.
