Can someone tell me the alt coins with high fluctuations throughout the day, so that I can make some steady profit in day trading?
Nothing. If you see the altcoin market right now. The market is bleeding in red. Most of the altcoins right now are declining. So you can't expect that you could get easy profit on day trade because people are dumoing their altcoins for Bitcoin. But actually it's the right opportunity to buy much cheaper altcoins to trade it for long or mid trade. Expect bearish altcoin market for weeks because people are going to hold their bitcoins to acquire fork coins to get quick money from that. After that, i think the altcoin market will be bullish again. It's hard to day trade when the market is bearish. So i suggest, HODL. I got some IOTAs and some SYS on my bag. I hope i could get huge profit from that in the future.
Could you explain why you think Syscoin is a good choice? I couldn't really figure out what makes it special so far.

High fluctuation always means high risk. You might stick to low market cap coins like PuertoLibre suggested, but you will always be on a high risk to lose a lot of money. To my mind, it's better to stick with somehow "stable" coins with a marketcap of at least 100Mln$ and above to be more secure. You might not make that huge profits, but steady little gains all the time.
