About me
I have been active in the financial markets since 2012. I started out on the Forex market, where I spent the first years — both the successes and the failures — of my career. With the rise of cryptocurrencies and the growth stories on the stock market, I broadened my portfolio and today I am active in the stock, ETF and cryptocurrency markets.
I focus on fundamental analysis, swing trading and long-term investment strategies. I have completed dozens of courses and webinars on trading and investing — as the saying goes, “so you don’t have to”. During my career I worked at the investment company Cyrrus, where I went through numerous training programs on the stock exchange, equities and ethical conduct in finance.
Unlike most of today’s financial influencers, I make an effort to provide quality content for free. But I am only human, so it is important to verify every piece of information from several sources — a rule I strictly follow myself.
Why trust me
Given the number of fraudulent offers online in the financial sector, I present only verified brokers with which I have personal experience and where I trade or have traded in the past. That is why every review contains not just a detailed assessment, but also warnings about possible risks and problems.
Hands-on testing
I have personally tested most brokers — a real deposit, fund withdrawal, checking the platform and customer support. I work exclusively with regulated companies (CySEC, FCA).
Real-world practice
I hold active accounts with the brokers eToro, XTB, Interactive Brokers and Fio e-Broker, which lets me offer a broad view of different platforms and their services.
