Yeah I think we jumped in at the same time, I earned a few cards but then they changed the rewards. Need to invest now to make SPS income. But I know people who have thousands of dollars of SPS. There is no way I will ever catch them.
But it's Decentralised structure means all Hive users benefit, so I make a little bit of sps stake it and the rest just sees my Hive account value grow from all the buy ins :)
Hive is an interesting place to be and there is a lot more potential yet to be realised.
