I'm not familiar with cryptos. I don't think they are anonymous,... wallets are connected to banks in some ways, so cryptos can be converted to cash and vice versa. But I was planning to experiment with cryptos, but I'm not interested in connecting my bank to a wallet service. Can we use registrars for this purpose? For example I buy my domain from Epik, and get paid by btc. I keep that btc at Epik, and convert back to cash at Epik, by buying my own domain and getting funds in USD, at Epik . This way there is a 10 percent loss (if btc price remains the same), but this way some other risks may be eliminated. Possible or not? Smart or stupid (probably stupid, ..but good for experimenting if possible) ......... Does anyone know how to play in derivative market? I don't. I don't even know how to buy stocks. (I heard stocks have nothing to do with having some kind of ownership rights at a company, they are IOU's, whatever it means. ) In the past 5-10 years people were all saying gold will skyrocket next week, and it never happened. Fundamentals don't matter. Weapons (of all types, including financial), and intentions of powerful groups matter. Landing on Mars, can be possible, but it can be totally fake, because it was done for prestige purposes,and failure couldn't be possibly allowed, so probably some graphics were created in advance together with media coverage, and whatever the actual outcome is, it would be advertised as success. .. Can we watch all that journey in video form, I don't think so. I suspect sending high resolution images from such a distance (further from sun), would be difficult (impossible?). Also 22 minutes of time gap would make commanding the vehicle close to impossible.
