There is nothing courageous and admiring about someone who greedily invest in cryptocurrency just because he heard that many investors who invested in it made millions from it. I see them as being selfish and unreasonable. Asides, from investing with the money that you can and willingly to lose, one should monitor the market and know how it flow and not just jumping into it.
Definitely we only invest some money that if we lose it, investment would be ideal if we use the money that we will not use in a relatively long time. Whatever happens with our investment, our minds can be a little quieter because we are not in a depressed state. Risking most of our money in investment for sure will give us a big presure that will lead us to make a panic decision when something unexpected occur.
