If you plan for a long term investment, then Invest your money on Ethereum and Waves, both platform are used by many tokens and assets. It's getting popular now.
But you want to be a daily trader, I can't recommend it. You can explore the altcoins thread and analyze what coin is good for daily speculate.
I agree, for long term investment you can invest on Ethereum and Waves but I would suggest to divide your money. Half would be for bitcoin trading and half would be for altcoin trading. As you can see the price of bitcoin is increasing almost every week for the past few months. And I'm not a fan of daily trading 'cause most of my coins are for long term, do a research and check at coinmarket which coins are mostly active for daily trading.
