Have no need to fear; if the price is rising, it means it's time to sell. Anyone who bought for less than 40k USD should aim to sell at this price, in my opinion. However, the subsequent gain is lower, but it is beneficial for traders to cycled this money.
And even if the value begins to rise, one will benefit, particularly if some of it is sold and the rest is kept for another hefty premium.
I sold Bitcoin at $49.9k. Now its price is about $43.7k. It would seem that we can buy it again and thereby increase the total number of coins in the deposit. However, it seems to me that the general decline may continue, we will be able to get a more attractive purchase price.
