This is the ripple xrp/usd daily chart
since May/June. A random strategy is to set a buy order at around 16/17c mark - as you can see it sharply dips every few weeks. Then when order is executed, set a sell order around 30 cents which also is touched every now and then.
That's a 75% gain. If we are looking at these charts this swing trade would take a month at most to execute if the sideways trend continues.
I personally will set at 18c and sell at 29c, as the lows are SLOWLY getting higher.
