In the old age,few centuries ago people uses some money system which is called Barter system to buy and sell their products.This system works like exchanging their products between two people when they are in need but they realized that that system has flaws and not suitable for everyone since if there is no demand for one's product he can't buy anything he needs so later they moved to currencies (paper money) until now people uses this as their main form of payment but in digital format but people needs to understand that this also has flaw of centralization so we need to move to the decentralized money for better life.Lets get update ourselves to use the crypto currencies.
The focus is on concentrating, so I think focusing is better than focusing. But in the concentrated market, we will be bound by so many things but we are still protected. Entering the decentralized market, you are free to do anything without the law. So I think the focus market is still safer than this market.
market centralization is all regulated by government, so that everything is under control. in contrast to a decentralized market, where pure demand and supply work. therefore making this market more risky
