When you buy into crypto just promise yourself that you will hold the coins for at least 10 years.
Sooner or later you will become a rich man and panic sell periods will be inexistant.
10 years is way too much to hold any currency, or even the property but the thing is that we invest the money, then for the initial month there are chances that the people will sell it in the panic because of thinking too much about the profits or fearing the loss. Now, remember that it is just all the mind game and you have to show your nerves at this situation. If you can get over the first month or so, then there are chances that you will not do any panic selling in the future.
