Indeed. MACD would be a much more appropriate technical analysis tool. That and of course moving averages.
What more does that tell us?
Both tell us that BTC/USD is in a severe overbought and strong uptrend stage.
The problem with using standard technical analysis tools on BTC/USD is that the BTC/USD market lacks the same level of depth and liquidity of say EUR/USD currency pair so there is more variability (volatility) which can really mess many technical analysis tools up.
I'd say stop trying to apply technical analysis to BTC/USD for now and treat it from a fundamental analysis point of view. You can apply technical analysis when the daily volumes of trades for BTC/USD reach a very large level.
For now "predicting" the trend depends largely on whether you know key bits of fundamental data that is relevant to the BTC/USD exchange rate (ie stuff like important bitcoin related news event, news of wider adoption, more businesses starting to use it, some big business adopting it, etc).
