But what is there to worry if the daily activities of the users are not disrupted? Of course there is. Exchanges that make fake bitcoins are really weak exchanges! And, trading in such an exchange is very risky! Therefore, it is better to do most of the transactions on the top exchanges according to the exchange rating on the Coinmarketcap site!
If intending to trade then a centralized exchange may be more reliable. but every possibility is not always guaranteed, right? still Bitcoin has value and it's irreplaceable once you sell it. Storing Bitcoin on exchanges without being traded is also risky. Most Bitcoin investors always keep them in their personal wallets and they pay off to keep collecting them as long as they see a decline. As it is currently happening Bitcoin is better kept in a cold wallet. I may have come across an exchange like the one you are referring to. But unfortunately, I forgot and in 2019 I found an abnormality where the price of Bitcoin was not the same as Bitcoin. I mean the huge price gap makes me suspect that such an exchange is trying to manipulate novice traders.
