Bitcoin was designed after the 2008 economic crisis. It is deflationary. The halving of output every four years will further reduce the supply of Bitcoin. The imbalance between supply and demand will further push up the price.
A Bitcoin ban is out of the question, and the death of the dollar is inevitable. What Bitcoin offers is an alternative when the market crashes.
Who cares if Bitcoins are banned? I mean if you know the use of Bitcoins, then you will excel in it. It doesnt matter whether BTC are banned or not. You can easily see the real life example in Nigeria, I mean there was a time when BTC was banned, but still most of the country was using it through P2P trades. Yes we need to just not misuse it. And regarding the advantages of Bitcoins, all know what it offers. So no alternative is there for Bitcoins as said earlier. Buy large amount of Bitcoins in this cheap price and enjoy profits later.
