Slush pool despite being the pioneer in bitcoin mining, currently only supports 2 cryptocurrencies, the aforementioned and ZEC which makes many users look for another option where they can mine Ethereum or Litecoin.
Outside of this this mining group has good security, and a simple and easy-to-use control panel for those new to mining, consulting other mining pools, compare the rates presented by Slush Pool and they are slightly higher than those offered by others. .
As everything currently presents its pros and cons, but it is worth noting that Slush Pool has been on the market since 2010 and also has servers in Asia, Europe, the United States and other strategic countries that generates trust for its users.
Speaking a little about security, I find it very good since it offered me two-factor authentication, among other features to keep my funds safe. The customer service is of very good quality, they answered my questions in a friendly way and I did not have any other problem with that later.
I liked the option of monitoring my funds through the mobile application since from my work I can consult my farm without any problem.
