Yes, right, the market selling price is now falling again, but this is only temporary. Don't panic, face it calmly and patiently, a pretty good strategy in my opinion is to sell some of the other altcoins you have or about 20% that you have, and you can buy Bitcoin / Etherum to add to your wallet as a long-term investment for you. Just a little more patiently, investing in bitcoin as a long-term investment will not hurt you.
