Bitcoin is great fun to day trade BUT it would be a terrible currency to learn how to day trade with. the liquidity is terrible, and volatility is terrible (and excellent  ). forex is a better way to learn (lower cost), but a lot less profitable. either way it is making a BIG decision to learn to day trade, because it takes years, and you can be sure that if you give up, you will give up at a big fat loss. I would also advise that you have developed your own ideas about trading before you set out, and figuring out things yourself is important in this game.

If you are going learn to trade on Bitfinex my advice would be (apart from dont!) let your low orders fill (rather than market order) and keep an eye on the liquidity (your exit).

bottom line, dont let day trading ruin the loot to be made from holding!
