I used the mobile able to do it, I see yesterday they created new “invite channel” called more or something like that. Use that one, I’m still skeptical to what the group can do to a market but I see the next pump is in 1 Days time so I’ll be monitoring what coin they announce and then watch that during the pump to see if it’s worth partaking.
Can almost guarantee there's a private core group that buys in many days before they announce to the main group what the next pump is. It's the same thing with most signals groups etc: Core group buys in at a low price, rest of the people get tipped off when that original group is already up 20-30%. Which is fine - you're still making money, buy you're also just a means for them to drive the price up so they can unload quicker.
Two other issues:
1.) It's a huge time drain listening to a few thousand people blabbering away,
2.) You don't learn much useful from these groups (trading, technical analysis etc.). The goal would be to buy in when that core group buys in or even before that - to spot opportunities that allow you to benefit from the masses driving the price up. With these pump / signals groups the noise:signal ration is just far too high and what you learn is almost nothing other than when to jump when someone says jump.
It is a nice way to get exposure to new projects.
That was just my experience of being in a few of these groups.
