New altcoin Rollblock is gaining momentum, raising $3.7 million in presale and challenging Dogecoin and XRP. 📉

- Dogecoin's year-end forecast is disappointing: the price remains in the $0.08-$0.10 range.

- XRP has also fallen short of expectations, trading around $0.50-$0.58.

Rollblock, with its GambleFi protocol, promises to be the new market leader.
