If history repeats again (as it usually happens) the downtrend will reverse and a new could form, confirming the exponential growth in the long term and BTC could break the $20k mark in a few months.
This is quite possible, especially if Bitcoin's scalability problems get solved (or at least the news of that come out) and considering the fact that there are only 6.6 million wallets containing above 0.01 BTC (~$100 USD). At 1.5 wallets per person there are about 4 million people holding Bitcoin . Only 2.3 million have above 0.1 BTC (~$1000 USD).
Feel free to post in the comments your thoughts on that.
