DGB mining reward is not high comparing to bitcoin, even the people are selling it just to cover the electricity cost but at the bottom some whales are buying.
Did you tell us to save DGB coins for future / investment, we have been doing it since 2020, Until now, but considering the current value of the bdg is trading around $ 0.0265, most likely as you say, don't know for sure, but belief answers all of that.
The more DGB coins listed on the trading exchange, the better the price, with a maximum supply of 21 billion DGB coins, with a daily trading volume per exchange of $ 3,884,255, as happened on Binance and if it is multiplied / exchanged, it could be that the DGB coin value can be traded, the value in terms of price can be higher in the crypto market.
What to say, which we never thought could happen in the crypto world, for example: 0.02 tomorrow or later could have a value of $ 3-10, hopefully in the future everything will be better than expected.
