It would have been better if they implemented doge or litecoin instead. These coins have still cheap transaction fees and you don't have to use second layer stuff which is not as user friendly as the first layer solutions. Doge has been a main stream crypto for years. People should use it as a currency instead of trying to get rich from it imo.
You and I know very well that they are only going to select the cryptocurrencies that are very popular. Bitcoin and ethereum are the most popular cryptocurrencies there is, and that’s what most of the people are likely to be making use of, so that’s what they would add to their platform.
Dogecoin and the Litecoin are not really that popular, most people don’t even know about these coins, except Dutch coin that happened to have a bullish trend this year, but even at that nobody is really interested in Doge coin, except for those who just wants to hop on it and make money through it, because of trend.
