Don't trust any pump and dump groups, they will accumulate coins, then announce a coin and dump on your heads.

Only pump and dump schemes that work in fairness with everyone has a RANDOM coin that is announced (some of these groups get decide on which coin to pump based on the last block number of a specific coin so it is really random). 


For instance/example: The hash for a block from LTC will determine the coin, out of these coins:
0=AIR
1=BLK
2 =AAA
3=BTM
4=LLA
5=NMC
6=PPA
7=GRC,
8=OSS
9=SBD,
a=OAO
b=EXP,
c=DKK
d=PPC,
e=ALK
f=VTC


this way it is fair for everyone involved.  Groups that do not openly do something like this is just picking a coin with low volume so they can accumulate and dump on you when they "mysteriously" pick the coin.

Buyer beware
