Trading is a shortcut to quick profits and high risks and losses. Trading requires a lot of time and puts your own money at risk.
And investing is a means of earning high profits in the long term. Why invest, there is no risk in investing and you don't have to spend much time and money. Only long-term investment has the opportunity for high returns of 4-10 years.
Bitcoin is known as the best currency of the present time and investing is one of the best means of earning profits from Bitcoin. Because if you can overcome the cycle, you may be able to earn high profits. A new investor should always be willing to invest in Bitcoin for the long term and invest in Bitcoin to make yourself and your money risk-free.
You are wrong with the risk free statement, there is nothing without risk even being alive is a risk because if you come out of your doorstep you're in risk of unknown, stray bullet could hit or something could happen just like bitcoin too.
Bitcoin has risk but those risk are secondary, bitcoin risk comes in form of Hacks, loss of private keys etc. So bitcoin is risky too but less risky compared to any other investments and another risk is that no body knows the next minute or hour nor day in bitcoin so there is no guarantee that it will profit you on future that everyone hopes in but we believe it because we have seen it from its history and past cycles.
