Dogecoin is a cryptocurrency created by software engineers Billy Markus and Jackson Palmer, who decided to create a payment system as a joke, making fun of the wild speculation in cryptocurrencies at the time. Despite its satirical nature, some consider it a legitimate investment prospect

My honest assessment is that I would not invest in something that people overall think of a cryptocurrency as a joke cryptocurrency coin but that said, if the joke becomes more accepted widespread, news worthy and truly global then yes gradually buy small amounts and invest in over time but not buy it just because famous people like Elon Musk say so, buy it sensibly with your brain and market research / analysis gradually. 

You should only invest in DOGECOIN with money you can aford to lose and does not matter if you do, if you gain and earn money from buying DOGECOIN then no harm done and profit from it.

DOGECOIN is not a sound investment but you can alternatively buy DOGECOIN on coinbase and give it a go for $50 USD. 

In the early cryptocurrency market, you can’t really go too far wrong, even if you double your money then the time is to withdraw it quickly into fiat cash for safe keeping, don’t think it will make you rich but quite possible you may get rich quite possibly if you gradually buy dogecoin overtime and in 5-10 years over time or more. 

All cryptocurrencies is a long term high risk investment but certainly worth noting DOGECOIN at present is a good cryptocurrency to buy.  Again, Don’t just buy it because Elon Musk said so.
