But why not buy ETH? I think eth is way better than dogecoin though, maybe his next step is going to be eth, if he does that the price of eth would go up, a shame I sold my eth 
he's not gonna buy a coin other than BTC and doge that's majority total supply of that certain coin holder is the developer itself.I think the reason he bought doge because there's lesser concentration of dogecoin to the whales' wallet compared to ETH and I predict that he's not gonna touch ETH like never.
