US, Japan, Denmark, Rusia, Korsel and Finlandia was legalize bitcoin. even DUBAI was apply blockchain at their daily activities like pay a taxi.
though blockchain can't be track, its private transaction. it make hacker easier to do crime like money laundry dll.

and then WHY MUST APPLY BLOCKCHAIN???

Wow.... Maybe if what you say happen.. Bitcoin will be die because cannot be mine again. And it will be bad dream for investor.

For better alternative we can invest to altcoin are support blockchain 2.0 dst.

If you want safe trade.
1. You must have know roadmap from their company.
2. You must have skill technical analisys for learn moving candle.
3. Must have skill fundamental analisys to know developing a crypto.
4. Use max 30% from your asset to trade altcoin and 70% or 50% at btc.
5. If moving market down.. Please dont panic.. Wait until bouncing and buy again to cover it.
6. If accord you it was advantage sell all.

I think that way can help to get profit.. And be patient trader.

During a company have good whitepaper and have famous developer, i think their blockchain will develop better.
but, there is no guarantee of certainly if we want to invest it. so use 30% from your asset if you want to invest.
