Ask someone you trust very much after you buy the assets to change the account password and tell you it in about 5 years. It's a very effective and reliable method. That's how I bought a car.

Hello crypto brothers and crypto sisters

Please tell me how to avoid panicking and selling an asset at a loss,
I tried to set a plan and secure profits, but FEAR takes over and the concern that now the asset will plunge into a deep abyss is great
and I sell. Is there any literature on this?
