all the benefits that you mentioned are correct, but we must not forget some of the risks that will be faced if investing in bitcoin, one of which is that we will lose all our money if the price of bitcoin decreases. so if we have bitcoin, we must continue to monitor price developments.
I didn't agree on the line that I bolded above, you've said that it will lose our all money if we invest on bitcoin when it comes the price decrease. Then don't be a dump if you sell you Bitcoin while it decreases the price in the market, it surely has a loss but not all your money unless bitcoin will have no value in the market. Indeed, you can ride a risk if you know how to manage of this, yes monitor the price in the market is one all you need and sell when your profit was there and I think you've nothing to lose.
I think the charts and candles on the market have already shown when to sell, thats why you have to know how to do technical analysis so you can avoid losses when prices will decline. after all, not always falling prices cause you losses, many people use it to buy more a lot so you can buy at a cheaper price and get big profit
