Hello folks!
I'm thinking about starting to trade with Bitcoin, but I see people saying that It's risky &
almost like gambling.
I think that I mis-understand the meaning of trading.
For me trading Is for EXAMPLE,
buying Bitcoin when It's at 550$ and
selling It when It's at 670$. This Isn't risky because If Its value doesn't Increase, you'll just have to keep It until It gets higher enough, Is this trading?
I would really appreciate If people clarified more! Thankx

You are almost right.But some times,big whales play their games,dump their bitcoins,create panic,make the price to fall,spread rumours,etc which creates a great fluctuation in bitcoin price.If you read the previous history of bitcoin price movements,you could get a clear idea.Good luck.
but to me i think now it has become difficult for the big whale to manipulate the price of bitcoin and chance the market. i think now it has become difficult for them because the users of bitcoin are increasing from time to time.
