Now that we've selected Ethereum as the Cryptocurrency of choice to Buy, let's of course buy it! We chose the parity with "Real" which is the official currency of Brazil, but you can choose the one that is best for you, regardless of the country where you live.
After choosing the desired option, there are two purchase options: Limit Order and Market Order... in the limit order, you can choose the exact price you want to buy ethereum, for example: U$14,000. Already in the market order, the broker itself will instantly buy your cryptocurrencies at the prices that are currently being traded.
The basic difference is that the "limit order" fees are slightly cheaper, as you, the investor, will provide greater liquidity on the platform, but this is very personal to each one. See how easy it is?
