No doubt big players always keep control on the market pulse and always play their cards carefully to make panic the people with roller coaster movement with sudden pump and dump but DOGE is little different with huge community support. I also hope in future it will show nice performance.
What do you mean by difference of Dogecoin with other altcoins? Dogecoin price is always fluctuating like other cryptocurrencies. It's the nature of cryptocurrencies. Even Bitcoin and Ethereum cannot resist the effect of whales and panic sellers. I don't think the community trust Dogecoin more than Bitcoin, Ethereum, Litecoin, etc.
