Lets give different example to explain the point.
You buy a bar of gold and pay for it $100.
The worth of your portfolio is $100.
Instead of trading with gold you decided to keep it assuming price will always grow. (like you just assumed with BTC when saying you need to grow BTC only)
But instead of growing the price of gold is just going down this year
after few months you are still sitting on your gold bar which is now worth only $60
You lost $40 of the value and not happy anymore keeping it forever.
With the BTC robot this would not happen. Instead of keeping the BTC forever, it would anticipate the price decrease and trade it into USD during such time so you would not lose but WIN.
