But how to make your token tradable ?

Here is what we called an ‘exchange’ comes into play

You need to list your coin on an exchange. There are two types of Exchanges : CEX and DEX

CEX (Centralized Exchanges)

Like OKX and Binance, users send their coins to the CEX, then trading happens there. Just like traditional exchanges.

DEX (Decentralized Exchanges)

DEX use something called Liquidity Pool and Automatical Market Maker(AMM). DEX is acutally some smart contract code manage two piles of pre-staking coins. The exchange happens directly between user and Liquidity Pool.

The easiest way to make it tradable

Go to Raydium, create a new Liquidity Pool, staking some tokens, then it is done.
