Your account is worth less because the price of Steem has come down from $4 to sub $3. When you upvote other peoples posts you are not giving them any of your money. Keep at it and stick around. IMHO, the value here lies in the delegated proof of stake blockchain (Steem). Regardless if the Steemit interface, Dtube, dsound etc all suck, the blockchain is far superior than others for many different reasons that I’m not going to list here. 4 years and Steem should be considerably higher imho.
