We've been here before, you are just making the whales richer, selling your precious BTC for pennies (crappy fiat). The storm will pass, hodl, or try to accumulate even more BTC, it's a great time to buy for cheap. We will make it this time too. Even if BTC goes down to $15,000 nothing is forever. Remember $20,000 down to $3,000? Been through that storm too. Remember, 1 BTC = 1 BTC. To the Moon!
This is the general rule but in reality, it is easier said than done.
Some of the investors who put their investments into BTC at least invested hundreds to thousands of dollars. This implies that the slightest movement in its price could mean a profit/loss on their part. But if an investor would put that amount of capital, they must have a contingent plan and a goal on their investments.
But in all honesty, I agree with you- BTCs are inflationary in nature. They are too precious to be sold especially that its price are relatively low in the market.
