Binance over HitBTC. Or anything other than HitBTC is good as long your local community of your country is using it. I have seen similar changes in DOGE and other coin prices on HitBTC previously as well.

Since the withdrawal for DOGE is not available, you cant also arbitrage it, meaning buying from a low price on one exchange and selling the same on another exchange at higher price. Obviously the owners are more clever than that.

In any case, you will need to change exchanges and I would suggest you to use a site like coingecko to keep track of prices than yahoo finance.
