Ethereum value is very low at the moment, i think its better to keep holding eth unless it grows to over 800 then you can invest or cashout according to your needs.
To hold the Ethereum has a chance to groe and getting bigger the value maybe that could be consider as a srategies. Although their are lots of process that needs to determine it is because we cannot say easy that would be ok. Holding or trading will always depends on your needs or capabilities so that you can think for different way around.
