I agree 100% because anyone make a profit through a trading but the important point is that they will know about trading many people have not knowledge about these things but they want to invest and they will invest into a rong token so definitely they will gain a loss so its possible you get a profit but main point knowledge.
Before starting to trade at least we prepare as well as knowledge and skills and that is the important thing,
it will be very risky if we don't prepare anything,
other than that we will easily lose money
Knowledge is most important thing and need many research when buying some coin like checking about road map and coinmarketcal is the best option to know about what new way for coin we buy. before I buy some coin I check on project telegram channel or twitter and see what they have new update for today or few day later, usually when coin have new moment like mainnet or have new partner will get pump price and many investors interested to buy.
