Ripple, like many other coins, had a bullish MACD crossover last week (where the 12 day moving average exceeded the 26 day moving average - signalling that the price trend is on the rise). Ripple has been consolidating nicely between $0.15 - $0.20 and has formed a solid support at $0.15. With the Swell conference coming up, the price of Ripple could increase due to the hype around the speakers and investors attending the conference. Speakers include Ben Bernanke (Former US Federal Reserve Chairman) and Tim Berners-Lee (Inventor of the World Wide Web).
Upcoming resistance levels are $0.22 and $0.27. I believe once it breaches $0.22, the momentum and the hype of the conference should drive the price upward and test $0.27.
