An even more serious problem with this type of cryptocurrency trading is the Exchange. The Exchange is the platform for buying and selling cryptocurrencies . These exchanges charge high fees, are highly unreliable (unregulated) and in most cases hide real scams. The Exchange seems to work well for some time (even years) but then it closes without explanation, obviously making all the cryptocurrencies of the customers and their funds in traditional currency disappear. Coinality guides you in these matters.
The best solution for trading cryptocurrencies is represented by CFDs (contracts for difference). CFDs are financial contracts whose value depends on an underlying. We can have CFDs on stocks, on raw materials and, in the case that interests us, on cryptocurrencies. The best CFD brokers provide CFDs on Bitcoin, Ethereum and all other major cryptocurrencies. From Coinality you will get all the supports and suggestions regarding all these.
The value of a CFD on Bitcoin is exactly that of Bitcoin. It is possible to bet upwards (gains if the value of Bitcoin increases) or downwards (gains if the value of Bitcoin goes down). Profits are proportional to the price difference (this is why we talk about contracts for difference) but they are multiplied through financial leverage.
