From my experience you can lose all from trading hehe for example your investment is 1BTC and you bought an altcoin. Lets say that that altcoin losses it's price and dies, and if that happens you lose all. On the other hand for example you bought a new altcoin @1sat each with 1BTC principal. after a few weeks or so, its price rockets up to @1000 sat each but its rare ahahaha. so that means you will get 1000BTC from that trade X1000 your capital. But it can go 2X or 3X sometimes and sometimes you only profit half of your principal depending on the move of the price of the coin you bought.
