I understand you might feel unconfortable keeping stocks for a long term, especially if you're going to be offline. But Earn H$ is not the answer. Sure, it helps a bit, but you gotta think bigger. When I started I never held on to anything more than 1 day, always keeping every cent ready for the big news to drop, but once you grow your port you need to get your money in play.
The best advice I can give you is to be smart, don't tie up your money unless you're absolutely sure it will at least give your investment back. There are plenty of short term investment oportunities out there: daily news, openers, starbonds.
If anything, if you want to tie some of that money without much risk, look at funds. They are (mostly) run by experienced managers that will give you a good return while you sit doing nothing. Granted, this is a longer term thing, but for example my current fund holdings have given me a 6.4M gain from roughly 4.7M investment. But still, there are faster ways to grow a port. You could also look at funds to learn from the strategy being used by each manager.
