I Have never seeing anyone who said, I made huge amount of money from trading bitcoin, the testimonies I always see or hear is see the amount of money I made from my bitcoin investment.
Trading bitcoin is not what you should be thinking of venturing into as a newbie, they should focus more on investing in bitcoin rather than just looking to make quick money from Bitcoin which in the real sense, bitcoin investment is not of such. Trading is another skill one can have in the crypto world than can make you money but although much risky than just holding on to bitcoin and watching your portfolio grows. Every etiquette of holding Bitcoin can also be applied to trading and the distinct difference between them is that trading is more risky than investing in bitcoin only.
