For sure those exchange platforms that do have lesser or low price of Doge does really restricted any deposits from external transactions because this is commonly happening whenever there are some huge gaps in price
on where platforms do mostly closes it up for avoiding arbitrage trading.

Also one of reasons is that it is lacking some liquidity or volume which simply means that there arent much people who had been trading on this platform in Dogecoin which its understandable that
liquidity is absent.

Be careful on making deposits because its likely you wont able to get it out.
