HF 21 was done a day ago but after implementing the code developers found a new bug in hf 21 so to resolve the bug found in hf 21 so developers decided to do another fork to make steem bug removal.
IN last fork there was a big problem in delegation to the fork and whales cannot delegate their power to bot so that they can make some reward so the steem team decided to make a great formula a new patch which is called new steem hf 22 has been deployed to steem and now steem is working very good i am trading now in steem engine because trading in steem engine is giving a good money now a day so do not wait just make .
