Digital Ocean is a great hosting solution, really. I like it for their quick setup, SSD and low prices.
But mining on 5$ DO VPS will give you about 2kh/s per core. And it's such difficult already to mine doges.
Better join a pool.
And for those who found my small advice valuable and saved some money:

Many thanks
go to server usa 2 and you will get 6 khash/s.
create 5 instances in total you will reach around 35 khash totally
now join a pool. you will get around 2,500 coins daily, this method is currently used by myself
