Which exchange has grown from nothing to big thing?

[SoftPotato]

Have you guys ever discovered or used any exchange or DEX some years 

back and now you randomly find out they are popular and a big thing now? 

I'm sure this has happened to a few of us that probably traded on some exchange because they listed a token you wanted and two to three years later the exchange is now way popular and a big thing. 

This ever happened to you guys? Makes you feel like one of the pioneers haha

For me it's Bitget, I started using them three years ago and now they are one of the biggest exchanges in the world with even 4m followers on twitter. Nice to see
