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.
You think bitcoin will still grow with time? I don't think that bitcoin can exceed $5000
For example I'll invest $1500 in bitcoin (0.75 BTC) and other amount in other coins. Is that good idea?
