check the new support of BTCUSD (4 hour timeframe ) buy above the 20 MA
this coming 2018 all US dollar pairs will become interesting ;)
If the supply will increase the demand will decrease the price will become cheaper , because no people wants to buy . But if the Demand of people in a one thing supplier can change the price it can go UP like this scenario you can see the big rejection then after a few day they become a bullish.
Some big investor will take their profit at the top and some investor will wait for the 20,000$ don't expect that the market will reach 20,000. if you buy the bitcoin and you are expecting to go back in a bullish trend, you can call you a gambler not an investor/trader.
I use 100 Moving average to see if the market have capacity to reverse then if you check my post there's a chance to reverse . If the closing price reach at the 20 MA just buy .
