Would you guys suggest for a beginner to focus on mining solely bitcoins? Or would you say that it's smarter to mine for the other digital currencies out there?
I would say that mining bitcoins is a very bad idea for a beginner, and actually for anyone not having huge amount of money to invest into specialized hardware
and good understanding of possible risks.It is possible to mine some altcoins (for example, Monero) with CPUs, but it still requires a large farm to get a meaningful profit.
