And for the altcoins, after buying altcoins, what happens if no one wants to buy them from you? You know a lot of altcoins aren't all that popular so how do people even sell off their altcoins? Can you even hodl altcoins?
yes I hold altcoins but not for long term. We must make our investment plan for each asset. There are altcoins that are suitable for the short term or vice versa for the long term and are quite safe.
If the altcoin is already listed on an exchange then you can sell it on that exchange. You can see the trading volume and you will see how much interest the market has in the altcoin you want to sell. The higher and more demand, the better the growth in asset value. it is like the nature of the goods being traded.
