Full time trading with crypto can be HARD! However, a lot of new traders fail due to two fundamental flaws.
1 - Not utilizing discounted trading platforms or functions
2 - Not utilizing stop losses (or setting stop losses in the wrong spots)
You may also add entering a position without the confirmation. A lot of noob traders, when the market gets dumped, they'll buy some without confirming a goos entry point. They forgot that the essence of indicators and other tools that helps a trader to be guided in their trades.
