Likely due to ppc arbitrage. It doesn't change anything in terms of spend and the return is the same, it's just that users click through different sources to get to the same destination.
This is unlikely to happen. I've been following this industry and have seen so many failures thus far, that Nautilus will not be anywhere ready for mining by 2019.
Depends. If the asset is digital, you can register the corporation in a tax haven through a offshore broker (Cayman, Panama, or St. Kitts), acquire the asset and then turn around and sell the corporation.
It seems that way. It isn't new money entering the market, as chart data across Poloniex, BFX and BTC-E shows the biggest inflow is BTC/ETH. It's just the same old speculators getting in on the rush of a cheap alt-coin with better technological potential thats riding on some good news about its partnerships. It's a bubble, but who knows where the top is.
My AirBnB experiences have all been poor, despite staying exclusively at 4.5/5 star reviewed properties. The lack of service isn't worth the extra savings or superior hardware. Hotels are so much more comfortable due to the constant service/follow up in case anything goes wrong.
