Bitcoin market is not stable, today it raises, tomorrow it falls. The most important thing is someone investing in Bitcoin to monitor the market, some people have the patient of waiting while some others due to fear when they see that the price is fluctuating might rush and sell, I will suggest we buy the idea of buying and waiting while we monitor the market. If possible monitor it when the price is low then you buy and hold.
If you are waiting for the price of bitcoin to be stable before you can buy or sell, it will take you a long time to see such opportunity in the market. You can buy now that the price has decreased to $118k and hold for long term because nobody know when the low price will hit the market again to be stable for people to buy from the low price, investors that understand the movement of bitcoin will not be afraid of the decrease or increase of bitcoin when holding it, there is no how you will hold bitcoin for more than five years without a good income from your holding, but when you allow fear to enter you, you will sell to regret because you allow fear to push you to sell when it's not time to sell to achieve your heart desire from your holding.
Since Bitcoin is volatile in nature, it is not advisable to have the mindset of waiting for Bitcoin price to be stable in the market before buying Bitcoin with your discretionary income, but eventually if any newbies or investors is still have such feelings by any chance that Bitcoin will be stable before they could buy Bitcoin aggressively that means such newbies or investors are definitely placed their focus on gambling rather than buying Bitcoin for a longer term, so no time that is bad of buying Bitcoin aggressively but buying Bitcoin now is better than buying later because we can't predict how Bitcoin price will be in 5 years coming.
