Everything's up in the air with bots at the moment. HF21 is changing the landscape a little, so until it settles and we see the effect on the different bots, its hard to know.
If you want to put it to work, I recommend delegating to @steemmonsters; which will give you a daily dividend in Dark Energy Crystals, which can be spent in game or sold for Steem on the steem-engine exchange.
Lots of stuff has happened in the last 2 years :)
