BTC = 0.12147030 (+0.00615145; +5.33%)
There are some interesting coins with a low price and a huge volume. EMC2, VOX, SYS, BAY are some of those, while I don't like ADA, despite the high volume.
Good luck!
I don't know who mentioned arbitrage trading, but I'm not doing it for sure 
I wonder if you gained profit from the recent spike of BTC price from $8000 to $9500
or you were just trading bitcoin to altcoin pairs?
either way it should generate good gain if you buy/sell at the right time, good fluctuation price
so, any chance you're going to share your trades history?
