I waited for more than a year and finally the dog coin exploded, reaching a peak of over 80,000 coins. Recently, only about 15,000 coins are left. I sold some and exchanged for mainstream altcoins, as well as some ADA, Polkadot, and after the dog coin exploded, I might be wrong for switching my holdings! But thinking about it, exchanging dog coins worth over 2 bucks, it might still be worth it when altcoins rise together!
