Hey, I asked once but didn't get a reasonable answer: where do you store your ETH coins?
Pump and dump coins don't need wallets. You keep them on your exchange account until you dump them.
ETH is certainly not just a pump and dump coin and there maybe some people who use it as such but then there is people who constantly pump and dump bitcoin too.Ethereum platform has paved way for the building of many cryptorelated projrcts which were not possible without ETH.
