Traditional Crypto Exchanges: If you see yourself as someone who has enough experience of dealing in the stock markets, traditional crypto exchanges might seem familiar to you. These platforms operate in a similar manner except for the fact that they deal in cryptocurrencies rather than fiat currencies. They also charge a small percentage of the trade in the form of their platform fee. Example- Kraken

Finally, always check, double check and triple check while trading – a simple tip that even seasoned crypto holders forget. When setting up buy or sell orders, make sure your numbers add up, as even the smallest of typos can see you lose an eye-watering amount. Also, when dealing with an exchange, make sure you’re sending coins to the correct address.
You could try this instead: Be sure to watch an exchange’s order book to better understand the actual prices you can get for the amount of cryptocurrency you’re trading. Consider breaking your order into smaller pieces to get a better price, or use a trading algorithm that lets you execute your larger order as a stealth order at the top of the order book.
Don’t be greedy. No one ever lost money taking a profit. As a coin begins to grow, the greed inside us grows along with it. If a coin increases by 30%, why not consider taking profit? Even if goals are set to 40% or 50%, you should at least pull out some of the profit on the way up in case a coin doesn’t reach the goal. If you wait too long or try to get out at a higher point, you risk losing profit you already earned or even turning that profit into a loss. Get into the habit of taking profits and scouting for re-entry if you want to continue reaping potential profits.
