Saving Bitcoin is the way to earn profit too, because the price is increasing insane day by day. So insteading of investing or trading them, just keep them and simply you're having the profit.
Yes, saving them or holding them will give you profit, but I think you are just being reliable on how the price moves and pumps. I think you can also risk your own money to invest, we can't just rely on the pumps that is happening since we don't know what will be the movement of the market and how will the price behave in the near future.
