Don't panic about the decline in Bitcoin and Ethereum because in my opinion Both are the best cryptocurrency currencies, you have to wait patiently because when both are declining because it will be an opportunity to buy it and hold it if you already have it.
and in my opinion, both are very good if you make a long-term investment to avoid panic and worry, you must be sure and optimistic that after the decline there will definitely be an increase, even if you have to wait a long time to remain patient.
