I believe that trading without understanding anything in trading is a bad idea and it's not surprising that you can lose all your money. You can start not with trading coins, but for example, try to buy coins supporting the mining PoS algorithm, thanks to which you get a percentage of the total number of coins you have on your wallet. The only thing you need is to buy coins, put them on a purse on your computer and have a permanent connection to the Internet. This is the easiest way to make a profit thanks to the PoS mining + price increase of the coin.
