how can you say the price of Bitcoin is not so volatile? all crypto assets have fluctuations, they have risks. indeed investing in bitcoin will be safer because it is very reliable. but that does not eliminate the risk of the highly volatile price of bitcoin.

if you want to invest in bitcoin, my advice is only for the long term. I have a principle, short-term investments will yield small profits. but the long-term investment will bring big returns.
So whenever you have the opportunity to buy, it means you have money to buy. it is ok to buy Bitcoins to increase assets.
