There are more than 4,000 cryptocurrencies in the current market. Many do not even know the names of most of them. Bitcoin and Ethereum are better known, so the names of these two coins are on everyone's lips. But when I joined the forum I could only sell bitcoin. No one buys etherium in Bangladesh. In my group, I said that since most of our payments could be sold in Etherdelta, I would get Ethereum, so I would tell everyone to buy Ethereum. Now many coins are sold in Bangladesh. Bitcoin and Ethereum are two very popular and best selling coins.
