He said that now many people are investing in it for more money. In such cases, if these people suddenly withdraw from the market, many will be in danger.
"That's our fear," the economist warned. "Since there is no authority, there is no room for more supply of money. So there is no mechanism to control when it collapses or goes up."
You don't drop a link to enable us to read the details of the information. Who are these economists? Want are their track records? How did they conclude that investors will suddenly withdraw all they have put in? Even if they sell it, other investors will still buy the coin. Bitcoin has gone through the process of buying and selling for many years and the system has never collapsed. I suspect that these are armchair economists who want to promote FUD.
He said, the central bank of Bangladesh is saying not to invest in Bitcoin. It is not an authorized currency. It is not worth investing in it.
This is not the first time central banks are issued such a warning. They are just scared of the decentralized nature of Bitcoin and want to promote fake news about the coin. The use of Bitcoin has kept increasing in my country even when the government restricts its use and discourages people from using it. Bitcoin has proved to be a hedge against inflation and offers better payment options which is why people will keep embracing it regardless of these attacks.
