I started today my experience with NiceHash today.
Is it still convenient?
Just in case you're still wondering about this, maybe you can clarify your question. Convenient in what sense? Easy to start? You also need to keep in mind that this thread is more or less their announcement thread, if you want to get a detailed review you can try to find other threads or make a new one. Most people will probably say that cloud mining by buying hash rate (if that's what you're trying to do) is not worth it though.
