There are a lot of HE tokens, but my experience of them is that their value generally trends down in relation to Hive, so I actually got rid of most of mine except for LEO and the SL tokens and a few others!
Got to be careful with these - if the asset value declines by 50%, you'd need a > 100% passive return over the previous year to make up for your loss!
Better off holding Hive which stays level at 10%!
