Yeah, MysteryWave is a good telegram channel, as I remember, I was there before. It's just sad they are now not active anymore.
You can count me in for this. I also believe there are a lot of traders here especially using the Elliot Wave method. Just make sure there will be some moderator to the channel to avoid spam or scams. I think it's better to drop the channel and it is open for everyone who wants to join.
