Can anyone start mining cryptocurrency?

Could you elaborate on the requirements and challenges involved in starting to mine cryptocurrency? I'm particularly interested in understanding if anyone can embark on this journey regardless of their technical background or initial capital. What are the key considerations for a potential miner to take into account, such as the type of mining hardware, electricity costs, and the current market conditions? Additionally, are there any regulatory restrictions that could prevent someone from engaging in cryptocurrency mining in certain regions? I'd appreciate a comprehensive yet concise overview of the process and any obstacles a beginner might encounter.
