So people pump a coin to increase the buy price- what do we do to increase the sell price?
The exchange relies on the # of buy orders that come in, to promote different emotions to people.
Most can relate to fear because its what we fear on missing out on - so hence people jumping on last minute which can push the price increase further.
Thats basically all youre looking for and being aware of these situations as a trader.
Emotion in trading = potentially bad decision.
The difference between the bid and ask is called the spread and they are there to stimulate a free market.
(What is someone willing to buy the coin for is the bid, what someone is willing to sell the coin for is the ask.)
(The order book, all those lines under each side of the trading screen, shows the supply(ask) and demand (bid).)
Why is there a big, or small, spread? What will the spread be tomorrow? How high will it go? These are called speculation (I.E. how to make the best possible guess)
For me trading is all about the numbers, I concentrate on those, they are exact, they are real and they never lie.
The mechanics of trading coin is not very different from trading stocks, there are lots of resources on stock trading so don't forget to include those in your research.
