when all the coins go down, I lose a lot because I bought a lot of coins, what should I do so that I don't lose a lot, please give your input, friend?
Stop and do not invest until it all goes to the bottom or many do not understand that something needs to be solved with the problems of the market.
Well, it's okay to sell to stop the losses. But everyone are thinking the same and if more people sold his assets then probably the price is slowly going down because mass panic sell of this downtrend.
