If you are satisfied with the present gains from dogecoin I suggest you change them to USDT or other stable coins, don't expect that dogecoin will keep growing higher, there will be bear season sooner or later, be prepared for that
This is right. The fact that the recent pump of dogecoin is very confusing, we should not put so much trust on it. The best way to do is to exchange your dogecoin to those stable coins like eth, btc and usdt. Bitcoin is expected to reach $60k ATH this year 2021.
