You can, but is not worth it, usually. Like you need to watch out for new projects that are like literally 2-3 days old jump in, mine whatever you can for few days and then move on. However its a hit or miss situation - most of those projects fail so the coins are worthless - you need to get lucky and find a successfull project that is not crowded - last year I mined about $100 worth of a coin for a day, sold them in a week, the project failed a month later.Thank you for your answers. So basically, every coin minning puzzle became really hard to solve that cannot be solved like bitcoin in the beginning?
I know the difficulty increases, but if there's a new coin in the market it shouldn't be easy to mine when it's new?
Is there at the moment any Coin that can be minable with cpu (with personal computer/laptop) that worth the enfort?
