Maintenance fees are too high in regards to the very low rewards you get per found block.
It's much better that you just keep your Bitcoins in your wallet as a long term investment. It saves you a lot time, money and headache.
Maybe that could be a good idea if you really don't want to compensate on cloudminings but its still risky to wait for more long months and hold your bitcoins in your pocket, but i think the best thing to do with that is to invest it so your btc will grow so if the time the btc price suddenly pump well yoy can earn huge profit with it since your doing a nice job handling and doing some great decision when it is on early stage on it.
