My suggestion will be probably you will buy both doge and bitcoin or you will just buy bitcoin only. The hype and the trend of bitcoin right no was seriously absolute in which many people are getting hype because of the sudden pump up of bitcoin and as well as the dogecoin which is been hype by Elon Musk as we are seeing his different tweets in Twitter. You can buy bitcoin and I am pretty sure it will be profitable as long as you are planning it to do as an long term investment.
