What's the formula for trading this digital currency TBT? 10 day moving averages and such?
There's a lot of factors actually. As more and more governments remove restrictions and decide how to recognize Bitcoin it can affect the market. The mempool size is also another factor because of the high rough ridin' transaction fees when I'm buying/selling.
World events also affect it, and for awhile every time Trump was negatively in the news it would make Bitcoin prices go up. There's also trends you have to look for but it's not just these that dictate how I buy and sell them.
Litecoin just basically follows the same rise and fall of Bitcoin right now, even though the technology behind it is way more scalable. Bitcoin is rapidly approaching some major decisions on whether this hard fork is going to happen or not. Ethereum has other forces impacting it than Bitcoin does. I could create a cryptocurrency right now on the Ethereum network, Ether is just the Ethereum currency for its smart contracts.
