Not buying the 50 Bitcoins at the price of 50 € was my biggest mistake. But who knows what would happen at the price of $ 1000. Selling at the 1k would be even more difficult. All of this is just a learning process, or it was one. Now you know a lot more about it, a simple hold would bring the most. Have nothing against regular trading, for which those who know their way around, but holding would be enough. And if you add up your compund interest, that's a lot more you can earn. Unfortunately, many want to become millionaires within the few months and make even bigger mistakes.
