I have never experienced trading on BTC or Crypto because I think it is better to trade on Forex:)
I will give a little information about trading on cryptocurrency.
When trading on an exchanger, the system is almost like stocks.
We like buying an item and stored, if the price rises, the difference is our profit.
If the price goes down, our goods are not lost but the estimated asset is reduced.
But the risk in this crypto is very big because a lot of cryptos that go down without support and reach very disappointing prices.
Example crypto dropped from a price of $ 10 to $ 0.001
