I believe some projects will be in underground cooking some crypto related trend that will change everyone taste soon. It's just a matter of time before they launch the trend.
They always come as wave, it will be denied and then some fast investors will risk it all on the project, the moment it boom, other developers will pursuit and start mimicking each other, before you realise, it will be everywhere but I hope not see the type of doge in Cryptocurrency again, that coin has led many to blindspot.
