I am a huge fan of DOGE which had been created with the first cryptocurrencies as a joke because it had seemed that there had been no use case at all. After a while DOGE started to have a value and I invested in it. It is quite easy to obtain it because there are lot of free oficials faucets. It is ment to be as free crypto for everyone which I really like and admire. The DOGE is now a real crypto traded at plenty of exchanges. It is fast with low fees and could be use in similar way as BTC. The only problem is that it is still not mainstream and somehow is still percieved as funny coin.
