I know that there are many individuals here in this forum that are always looking on cryptomarket price for the crypto that they are holding. Always hoping that one might get a good market price increase. This is why one does overlook on real number of crypto that they are holding because they are always looking on the equivalent of the crypto to fiat money. It is not like that because the real thing that you should look is the number of crypto that we know it is not changing for example you have 6 BTC @ 6k USD and eventually market price drop to 5K USD per BTC. Even if market price drop you still have 6 BTC and that is not changing and you should not worry. You have to get worry when you have 6 BTC and after seeing some time you will have 3 BTC only. That is one thing that you should worry because there might be one getting into your digital wallet and transfer your BTC to other digital wallet.
I also know that, the amount of bitcoin in the wallet is not reduced, but the value is reduced. for example having 6 btc with a total value reaching $ 60k, then when the market falls and the exchange rate decreases to $ 30k, of course that is a big loss. yes there is still a big chance to go up, and while the amount of bitcoin stored in the wallet does not decrease, everything will be fine.
