I want to start an ico on the ERC20 network. The ico will be available for three months for example. For that I have to write a smart contract. That is clear to me.
It is only not clear to me what happens when the ico has ended and then a couple of months later I want to sell the token completely publicly (for example, the coin can be sold on uniswap but also on an exchange). Do I have to write a new smart contract? Because ones you have deployed a smart contract, it can not be changed anymore.
You can create a trading pair for your token on SushiSwap which is a decentralised exchange that can trade any ERC-20 token.
To have a market, you need to provide liquidity on both buy and sell side and have somebody to act as a market maker. They then buy your token from you.
(Assuming anybody is willing to buy.)
