Doge is literally a joke. I'm sure you can make money, but their are true Alt coins out there worth investing in.
I've rolled nearly all my money from my robinhood account to coinbase in the past few weeks. Stocks were too much for me to keep up with. Alts have their own risk, and maybe we're in a Goldenage and just don't know it yet, but literally everything is taking off in the alt coin market.
GRT - up 844% in a month.
SNX - up 100% in a month. Bought this one thanks to
@TheDirtyWord
KNC - up 140 in a month.
Every 2 weeks or so I rebalance the book. Converting one coin to another is free. Say one gains $500. I send $250 to BTC and the other $250 to another coin that under performing.
