If you're just getting into memecoins be very careful with joining any alpha groups.
There is always a hierarchy in the group, you are not going to receive the contact address at the same time as everyone else. Bonds have formed, there is always a top dog then his minions and then you and the other bottom of the barrel members.
It's possible that the group manages give a coin some traction and create enough buy pressure after you're already in for you to make money, but if not then you're exit liquidity for the others who got the contract address before you.
A lot of groups create no traction on a coin at all and rely on a constant rotating group of bottom of the barrel members to be exit liquidity for the others.
My advice is to simply stay clear of them all together.
