No idea who this lot are but they've partnered with established names to facilitate this.
They've been around for about 1.5 years. They were the first ones on the market to offer leveraged BTC, ETH, etc. tokens. Binance had their tokens listed for a while, until they ended up copying FTX's idea and listing their own instead.
I've always found it very strange why so few people have tried to pair crypto trading with stock trading.
There's always been strong demand for stock CFDs among crypto traders on the unregulated market. I've known dozens of people who used 1Broker or SimpleFX for stock trading, and I always had great experiences with liquidity on 1Broker during the couple years I was trading there.
I think services naturally pursued CFDs instead of crypto pairs because they mimic the real underlying markets, dollar for dollar. That's what traders want because they are charting and trading based off the real market pairs. Dealing with things like BTCUSD fluctuations on top of that is really horrible for manual traders. They'd be eaten alive by arbitrage bots.
I'm really not sure how much traction we can expect this to gain, but I'm curious.
