There was time when crypto market was on it's peak.  A large number of bounty hunters were busy on twitter regarding different coins / projects.  Others were watching a number of posts on twitter and so were knowing about crypto and bitcoin too.
Many new people were investing / buying bitcoin with the objective to gain if bitcoin price rises.  These people may also be engaged in writting on twitter about bitcoin.
Now crypto market has fallen to new depths. Most of the bounty hunters are away.  So we hear less about crypto and bitcoin.  Certainly it has shown these results on twitter / facebook / instagram too.
