I've read some ideas here and thought it was really a good time to do a review when 2018 will pass soon.
Moreover, will Bitcoin totally recover on 2019?
The hype of crypto currencies has ended in 2017, so Bitcoin price slowly declined during 2018. It is needed to wait for May 2020. Perhaps the halving of mining rewards will have a positive impact on the BTC price. I suppose Bitcoin can grow to $10K, but I doubt that BTC will reach $20K in 2019.
