Trading has not yielded the results I was looking for, at least not yet. I seemed I came up with a trading system that worked and i also was making money but there was 2 problems that has made trading difficult.

1) One exchange We were using was Cryptsy. That exchange went out of business and would not let be pull away my coins, so they were lost. The lessons is don't trust exchanges.

2) I set requests high for sells so I can make a good profit and then rebuy lower. The problem is that Bitcoin has risen so high that my sell orders went through but the price kept rising. Then it was hard to find an entry point.

For these reasons, I only do a little amount of trading and I mostly maintain.
