Bitcoin is not only suitable for bull market, but it will also become a promoter of the bull market. Why? Because ETF! This is the most likely possibility of driving the market this year!
It's not going to happen fella. If people were still having some degree of hope that the SEC would let an ETF come through, they can thank the drama/fud around Bitfinex for slimming down the chances even further. All the market making happens on non compliant USDT exchanges, so what do you think the SEC's thoughts are right now? I can't even blame them to be honest.
The only increase in price this year will be related to Q4 seasonality, so you can be sure of the fact that most of the increase we'll book in the last months of the current year will be undone in the first months of 2019. It happens each and every year. It's a returning crypto cycle. Look up the charts and you'll see that it's true.
Buy now. Sell in December. Buy back in March or April. Or keep hodling if you don't want to speculate.
