Bitcoin is the Alpha and the Omega. All alt coins shall forever bend the knee before it.
Bitcoin is the revolution - It is the internet and the shitcoins are the dot coms; >95% of which will be like shooting stars, burning briefly before turning to ashes. But Bitcoin shall endure ;)
The only thing that worries me in the short to medium term with regards to Bitcoin is Bitfinex and their tether coin scam. Potentially a MtGox 2.0 in the making. Was thinking it could be the event that manifests to fulfil the "DANGER WILL ROBINSON" scenario that @haejin TA was alluding to a few weeks ago.
We'll see. The time will tell. I'm calling $500 BTC before the end of 2020.
Many of the alt-coins have far better tech than BTC. The real bubble is BTC which would simply be just a few pages in the future history books. If You think highly of BTC, go ahead and pour your money and lock it for 3 years.
