Can the following problems be solved?
most of the following aren't even problems to be solved!
- Bitcoin is not based on "underlying" for the transaction, the risk is high.
elaborate, this is too vague.
- Bitcoin is very close to the possibility of money laundering and terrorism financing.
bitcoin is a tool, and tools are not close to anything. people use them for different purposes but that doesn't defined them. for example if i use a fork to scratch my ass that doesn't make forks as butt-scratchers, a fork is still a kitchenware!
also as alyssa85 said the amount of usage for anything illegal is negligible when you compare it with how much fiat like US dollar is used for terrorism.
- Bitcoin has no "best practice" and international standards to ensure the security and efficiency of the organization.
again bitcoin is a currency you are expecting things out of it that are not even related to a currency!
- Bitcoin has no central entity as the subject of arrangement, no party is responsible.
that is the definition of a decentralized system. there is nobody in charge. there are a set of consensus rules that the whole network agrees upon and they all follow it and that makes it trustless and secure.
- Bitcoin price is determined by the market depending on supply and demand
name any object that comes to your mind from a loaf of bread to an aircraft carrier, price of all of them is determine based on supply and demand.
- In Bitcoin there is no consumer protection.
repetition of the same thing as above.
