Currently I mainly use the number of crypto that I have to invest. Particularly for bitcoin I can convert to cash in my country so that I can buy the things I need to use. The exchange of crypto with other assets is very easy so I feel very satisfied that I have invested in a very practical financial market.
I keep holding some of it in my wallet. I also sell some especially when I need to buy new things that I need. I liied holding my crypto especially when I see changes on its price everyday because by that sometimes it increase more its price so when I sell it I get more profit. Only bitcoin was the crypto currency that I invested because it was easy to convert into fiat.
