I only started experimenting with the BTC micro this year. Used to play with the Micro Ether beforehand. These were badly needed. Everyone HATED the 5-coin thing. Remember when the micros were first announced here just a few years ago? There was a lot of bitching about CME's fees and poor liquidity.
May 2019... CME index micros started trading after being announced a few weeks prior. I started this index trading shit a few years too early. God damnit shitfucker fuck all! Ack!!!!
