BTCUSD approaches apex of triangle- will it break up or down?

As BTCUSD approaches the end of a triangle pattern (coming roughly the end of July), the question will be- is Bitcoin going to break up or down? From a technical standpoint, this is fairly unknown. Using fundamental analysis, I am still overall bullish on BTC for the next year or two and do predict it'll break up at this point. Cryptocurrency's mainstream acceptance and sector growth over time will have BTC (as the most well known and marketed cryptocurrency) rise up significantly and remain the most dominant cryptocurrency well until the end of the next bull market, before later generation cryptos like Ethereum (ETH), Ripple (XRP) or perhaps even EOS (EOS) take over.
