Is there a way to get out of this game by getting the little I have "earned"? 20k sat, 120 Doge and 1.8 million LTC. They aren't at all big amounts, but they should belong to me. Instead, because of the crazy limits, they will stay in the site owner's pocket forever.
Yes there is.
You can use the market to exchange all the different cryptos for just one, i.e. all the btc and all the ltc for doge.
You might lose a bit of value there because the market is user to user and you will have to offer a good deal to find a buyer, but with that you should be above the withdrawal limit of doge and then you can withdraw that.
