Wow, so you are even asking for that for free? No one is going to give you the real link to a group that is pumping/dumping coins for free if that is what you are asking for (if they require a premium membership o course)
I am into 1 group and it's decent looking to join some more.
And most of them are scam, i do not understand why you are looking to join one of those, they are a waste of time + money, i do not suggest you to join any of those if you do not want to lose anything.
Can anyone post the group invite link pls?If there are chat groups elsewhere then it's fine too.. I'll download that particular appI just think chat groups increase the knowledge and will get to know more...
Just try to make your own research on google, you will find a lot of them, but most of them are crap.
