The bitcoin/dollar (BTC/USD) chart is currently showing what looks like a classic bear pennant flag pattern, which could mean a further leg down in the next few days, so look out for confirmation of a breakout and potentially short the bitcoin price to profit in the short term.
My long term outlook for bitcoin however is still bullish as I believe lots of institutional investors are buying up bitcoin whilst retail investors are selling, and the approval of a Bitcoin Futures ETF product in the first quarter of 2019 could mean that billions of dollars of investments pour into bitcoin, raising the price to a predicted $40k and $65k in 2019.
NOT FINANCIAL ADVICE – PURELY MY OWN OPINION.
Don’t invest any money that you cannot afford to lose. Cryptocurrencies are speculative investments and are highly volatile.
