For now, I avoid investment or trade in cryptocurrency because the speed of rising and falling can not be controlled and this is very dangerous for me personally including mental health and personal finance. I better invest in gold in order to get ROI that is clearly visible in front of my eyes because cryptocurrency can go down and rise at any time.
For example, I invest in ETH with a value of $ 100, then tomorrow it drops to 90, 80, 70 dollars and for rising we do not know when, while for daily needs we definitely need money or profits from our investment in ETH.
