I have some DOGE, received from faucets. Not much just around 500.
After the increase in the transaction fees of BTC, I have thought of converting my BTC and LTC to DOGE for the transactions and keep them as DOGE. On the second thought, I thought of converting my DOGE to LTC and keep.
Dogecoin has a relatively lower transaction cost than bitcoin and several other altcoin, and it would be cool to transfer your coin using dogecoin. Keeping your coin in dogecoin is fine, if you're holding for a short while, a month or two is cool, as dogecoin is still pumping hard and you can make a quick bucks from the value appreciation. But I won't advise you hold dogecoin for long term, bitcoin and ethereum should suffice for long term hold.
