It is certainly possible to trade without experience and knowledge, but not the fact that you will remain with your funds, since without experience and knowledge you will not be able to analyze the market and choose a good asset for investment, I agree that there are self-taught people who try at their own peril and risk trade and learn from your mistakes
I think it is happening now as bitcoin price is gain to the high price, and many people are shocked to see the higher of bitcoin price. I am afraid that people who don't have enough experience can get into a trap by buying bitcoin at a high price. If that happens, they need to wait for more until the price can back to the price they bought bitcoin. These moments make us careful to decide because we can miss the chance to sell bitcoin at a high price if it's not.
