Who is a trader and who is a merchant
In cryptocurrency, you often hear two words:
trader and merchant.
They play different roles on the exchange
Trader
A trader is a person who buys and sells cryptocurrency to profit from price fluctuations.
He analyzes the market and tries to buy cheaper and sell at a higher price.
Example
Trader buys
at a price of $2000.
After a while, the price becomes $2200.
He sells cryptocurrency and makes a profit.
Merchant
A merchant is someone who works in P2P trading.
He constantly buys and sells cryptocurrency for fiat.
Usually, merchants earn from the exchange rate difference.
Example
