byteball airdrops really are terrible, I don't know whose idea it was to constantly give away to people who don't even hold the coin so people only interested in holding BTC and dumping byteball immediately get rewarded on a regular basis, it's a terrible setup. Bitcore is a good example because it's a % based on your bitcore holdings so it encourages people to hold and accumulate. It makes no sense at all to keep rewarding people who just dump right away. I'm very disappointed with the way it's all turned out.
Byteball airdrops are now mainly for Byteball holders. Linked BTC gives very little Bytes.
