The pool has been around for over 7 years. I have worked with it several times and only stopped during times when mining wasn't particularly profitable. Now, with Bitcoin and other cryptocurrencies rising, the pool has become relevant again. You can mine various coins here, but I mainly focus on BTC and VSN. It's nice that there is smart mining – the system automatically switches to the more profitable coin. The income calculation also varies. If you have enough power, you can mine solo, but if not, it's better to stick with the basic PPS+ (although I prefer PPLNS, as the fee is lower – 2%). The minimum withdrawal amount is quite reasonable.
