I don't get bitcoin trading. I guess I don't even really understand or believe in it. I guess you are in safer hands trading a bitcoin product from CME, than the actual bitcoins themselves in the spot market involving shady bitcoin exchanges/dealers with routine news of theft and all of that shadiness. Ultimately, bitcoin is just another ticker to trade on. A very volatile one, yes. But why trade it at all? Why not just trade options of any other instruments? Any ticker of any instrument can do. It's just a thing that has a price change you're trading off of. And you can play the volatility and leverage you desire with options and futures. Why specifically bitcoin? I don't think I will ever buy into it. Now, there can be a 'use case' for those in the spot market, as they believe bitcoin to be another form of currency that is safe. That's all fine and good to 'diversify', the same way a rich person may own physical gold bars. But for the traders who trade just bitcoin? What's the point? Futures on indexes or commodities are juicy enough. Options on futures even more so. There is no need to jump onto a new thing called bitcoin. Just another pointless ticker. On that note I'm getting tired of all the mention of bitcoin now in the media. I don't want to hear it because I don't care about it at all. It is actually annoying me. You turn on financial TV and they sometimes talk about bitcoin this that. I don't care. Shut up already. Or when people talk on feeds about the S&P, they mention bitcoin too. Shush.
10 limit up and 100% is not enough to cover 100% margin. Why not 100 limit up? Then broker must pay the long. There is no limit to limit up in bitcoin.
