There is no crypto that is stable, crypto will always be volatile because of its anonymous character. If you want to invest more stable coin, you can try USDT, the up and down in prices is not so deep.
I totally agree with you that nothing is eternal, just the price fluctuations in the market. And now the price of bitcoin is very low in the market and according to my observation, it will take a long time to see the price of bitcoin increase again.
