RE: Is it better to have SPS or HBD staked?

I have a bit o HBD, for the long term, a bit of SPS, to farm the remaining airdrops, and BXT, that also gives 20% to 30% a year in HIVE.

I like both 3 and hope there will be another way to "farm" or "mine" SPS after the airdrop is over. HBD and BXT probably will keep the high APR for a longer period, but the airdrop seems to be limited.
