If your earning stay at 2 steem/day, you will be able to get your 300 steem back in about 5 months. That's really fast IMO, which is good as an investor as it's also passive.

In my case, since Leo tokens were dumped at a very low price around 0.075 to 0.09 Steem:Leo, the tokens I accumulated were around 4500 Leo at around 350 steem. Currently, this averaging me a curation reward of around 25 to 30 Leo tokens. The downside is that it takes my time and effort unlike the miners that earn by themselves.

Some would prefer passive while others prefer active. It all depends on personal preference.

Thanks for this detailed report, it has given me an insight on the actual returns of Leo virtual miners.
