Yes, it is an unlimited version and won't expired and hence until today many of us here in this channel are still using it and testing without any major problem. One word of advice though, yes it can be a nice EA and able to yield some profits but, it can also be dangerous too if you try to use higher risks trying to get bigger profits within a shorter period. Whatever you do, just learn to be safe (by minimizing your risks) and stay safe as always. Better be safe and sorry.
