HBD is better and safe because, in spite of bad market the price looks stable and it also gives 20% solid APR.
There are many decent second layer tokens that are good to invest. But my preference may not be a good one for you. So you have do your own research and find out which one suits your niche.
I don't want to give names directly but any project that has more than 2 tokens can be a potential Ponzi. Just my own perspective. Please DYOR
Splinterlands safe? (DEC and SPS)
Rising Star has 2 tokens as well? (Starbits and Starpro)
Rising star is definitely good I think they did not go beyond 2 tokens.
Splinterlands has so many tokens. SPS, DEC, Vouchers, License, Etc. It is a big game but not sure what to say. I'm still staying invested.
