Bitcoin worth today (review of last 12 months) according to CoinReview:
Many
 exciting developments are on their way. The Lightning Network is now 
live which enables payment channels with BTC, Rootstock will implement 
smart contracts on top of the bitcoin blockchain, and Drive Chain allows
 sidechains. Additionally, Schnorr Signatures and MimbleWimble will 
significantly improve privacy.
Bitcoins main
 goals are security and stability. Because of that, innovations and 
improvements are added only after years of testing and exploring. 
Everything needs to be fully understood before it is implemented into 
Bitcoin Core. Altcoins may be getting a short-lived technological edge 
by skipping the trial- and experimenting phase, but Bitcoin will catch 
up when it is time and will implement the best features.
BTC
 grew from a price of under 1$ to over 8000$ and a market cap of over 
130 Billion at the time of writing. And the opportunities are far from 
over, mass adoption is not yet reached, and there are several ETFs 
filled right now. ETF stands for Exchange Traded Fund, which is a 
financial asset that can be purchased on the stock markets and which 
holds the underlying asset. Once the first ETF gets approved, it is 
possible for investors to invest in 
BTC without going through the struggle of storing the asset themselves. 
When the first Gold ETF was installed, the price for an ounce of Gold 
went through the roof. And there are many technological developments 
under construction right now. There is more to come for BTC.
BTC
 is King and will remain King. The only fully decentralized and 
leaderless cryptocurrency and the only one which qualifies as a SoV 
(Store of Value). With many exciting developments on the way we expect 
BTC-dominance to rise and Bitcoin to cement its status as the most 
reliable and secure crypto asset.
