Hey. Don't worry, you can easily buy Bitcoin and any cryptocurrency you want. I advise you to read the bitcoin guide and if after that you still have any questions, then you can write them here. Although I'm pretty sure this guide will answer all your questions because there are many different ways to buy bitcoin. Good luck!
I just recently started to get interested in cryptocurrencies and I'm just taking my first steps (I've registered on an exchange, etc). I have a question: are blockchain and bitcoin the same thing? If I understand correctly, blockchain is a technology, and bitcoin is just based on blockchain technology, right?
