to be honest, I wonder how until today dogecoin manages to stay in the 34 position of coinmarketcap and other more useful altcoins are in a position far below dogecoin. What motivates people to buy dogecoin? I wonder about that. In the past I used to collect dogecoin on faucets and then switched to bitcoin and playing dice was more like fun for me. But if I think like an investor I wouldn't buy dogecoin
The answer to this is simply the use case of dogecoin where some of the major gambline sites accepts them to gamble and the low transaction fees is another factor and those who are new to the cryptocurrency space have a coin that will help them to understand how to store the coin in their own wallet and dogecoin is a perfect coin for all those because of the low valuation. Dogecoin might not be a speculative coin but the price rises once in a while when the altcoin market rises.
