SEARCH VACUUMS / AVOID MAINSTREAM NARRATIVES. 
mainstream = too many people for the same resources. 
vacuum = many resources for a small amount of people. 

NFTs (BAYC / PUNKS) become mainstream - almost dead. 
AIRDROPS become mainstream - in a coma. 
MEMES are slowly becoming mainstream right now - you know the end.  
Tap-to-earn will disappoint millions of people quite soon ( maybe except DOGS) 

Play-to-Earn though looks almost empty right now. This is where I will go. Already there tbh. Up until it once again become mainstream again.
