I believe the blockchain technology has potential, I believe crypto's have potential. However, for an ordinary person it's almost impossible to pay around $4000 for 1 bitcoin. I don't think governments can just ban bitcoin because they have to shut down the internet, but I fear through regulation and law they can make exchanges illegal (like China did) or perhaps tax every transaction. They will impact the price significantly. Since Bitcoin and alt coins have gone up so much since the beginning of this year, I am very careful investing. The reality is that nobody knows if prices will drop or go up. Personally I think Monero is a better coin in terms of privacy and is undervalued. I'm investing in Monero more when Nano Ledger S will support it! Also wondering what will happen with the fork in November! Perhaps we should also not fear this fork.
