I have some BTC asleep in my wallet doing nothing, therefore I want to put them in work to increase their value.
I've already looked into crypto trading but that requires spending much time reading about the projects to find good ones with potential and staying up to date with it, however my main concern is that I don't have much time to follow up on them :-/
Also thought about running a Loan service, however it takes as much time in validating the loans and keeping up with them, not to mention with my current trust it's highly unlikely to find a valid loan since they'd go for more trusted users.
My final thought was lending my funds to an existing loan service for a small return, which sounded good idea first... but I couldn't find a loan service that seems to be short on funds

Anyone got other ideas that will get me some revenue without having to spend much time following up with it? something set & forget for couple months (maybe check once every month or two)?
Loaning is one of good idea. You share some fund to all others and can able to get more interest from it. Next to that trading will works for this time. Due to tax day in US most of the people will convert the BTC for fiat.
Marketplace will boom back for few days then later we will not be sure about the later days and after it.
If you believe you can mine the cryptos with managing the difficulty you can invest on that too.
