It was also quite the monopoly of the P2P Bitcoin market which I never liked, so better that it shut down and paved the way for better alternatives. Similar to when there was a monopoly over a centralised exchange like MtGox, a darkweb market like Silk Road, a Bitcoin mixer like ChipMixer, or any other Bitcoin-based service. The ecosystem only gets stronger once the leading horse is taken down and the monopoly ends.
Towards the end, say the last couple of years, it was not that big.
First they got rid of the P2P face to face cash options. Then they started blocking people based on region, then the KYC.
So many better options exist. They kind of did themselves in.
