Emotional patience is the key, does not matter whether you are in crypto or other markets. Cryptocurrencies have many dips along to the top. If you sell in a small dip then you do not get used to those dips. You should invest in cryptocurrencies which you believe that will worth a lot in the future. Not in pump and dump scenarios. If you invest in once to those pnds then you get suspicious of every crypto that may be the pnd. Find yourself a really good futuristic crypto and invest in it.
